Stock photos are ready-made images that photographers upload to a library so other people can license them, either for free or for a fee. Used well, stock photos for social media fill gaps in your content calendar, illustrate ideas you can’t easily photograph and save you a shoot. Used badly, they make your feed look like everyone else’s and can land you with a copyright bill.

This guide covers what stock photos are, how free and paid libraries differ, the licence terms that catch businesses out, and the simple ways we customise stock so it looks like it belongs to the brand. We also cover the times when only a real photo will do.

Stock photos are licensed, not free to grab

The most important thing to understand about stock is that you never own the photo. You buy (or are given) a licence, which is permission to use it in certain ways. The photographer keeps the copyright. Break the terms of the licence and you’re using someone else’s work without permission.

That’s also why you can’t just save an image from Google Images or another company’s Instagram. Being visible online doesn’t make a photo free to use. Photographers and image agencies do find their work being used without a licence, and UK businesses regularly receive letters asking for payment after the fact. The cost of that letter is almost always more than the licence would have been.

Free and paid libraries each have their place

There are two broad types of stock library, and we use both depending on the job.

Type	Examples	Good for	Watch out for
Free libraries	Unsplash, Pexels, Pixabay	Backgrounds, textures, scenery, general lifestyle shots	Popular images appear everywhere, and releases for people and property aren’t guaranteed
Paid libraries	Adobe Stock, Shutterstock, Getty Images, iStock	People, specific scenarios, ads and campaigns	Different licence levels and editorial-only images mixed into results
Built into design tools	Canva’s free and Pro libraries	Quick social graphics	Content can’t be used in a logo or sold as a standalone print

Free doesn’t mean rule-free. Unsplash’s licence lets you use, modify and share its images commercially without credit, but it doesn’t let you compile them into a competing service. The Pexels licence goes further and says you shouldn’t show identifiable people in a bad light, suggest that people or brands in a photo endorse your product, or use images as part of a trademark or business name. Canva’s licence lets you use its content in social media and marketing designs, but not in a logo or trademark.

Paid libraries cost more but give you a wider choice, better search tools, and generally clearer paperwork about who appears in the photo and what you can do with it. For anything going into a paid ad, we lean towards a paid library.

Know the licence types before you download

Licence names vary from site to site, but most fall into a handful of groups.

• Royalty-free: you pay once (or through a subscription) and can use the image many times without paying again. It doesn’t mean free. Shutterstock’s standard licence, for example, covers social media and online use with no limit on views, while its print use is capped at 500,000 copies before you need an enhanced licence.
• Extended or enhanced: a pricier licence for bigger print runs or for putting the image on products you sell, such as mugs or T-shirts. You rarely need this for normal social posts.
• Rights-managed: a licence priced for one specific use, such as one campaign in one country for a set time. More common with high-end photography.
• Creative Commons: a set of public licences. CC0 means no rights reserved. CC BY means you must credit the creator. Anything with NC (non-commercial) in the name isn’t suitable for a business account.
• Editorial use only: covered in its own section below, because it’s the one that trips people up most.

Always read the licence on the site you download from, as terms change. Save a screenshot or the licence file with the image so you can show where it came from if anyone asks.

Editorial-only images aren’t for marketing

Paid libraries carry a lot of “editorial use only” photos. These are images of news events, celebrities, public places, branded products or crowds where the photographer hasn’t got permission from the people or brands shown. Adobe Stock, for example, says editorial-only assets can’t be used for commercial purposes such as ads, promotions or merchandise, even with an enhanced licence, and only minor edits like cropping and resizing are allowed.

For a business, almost every social media post is promotional to some degree. So as a rule of thumb, we treat editorial-only images as off limits on business accounts. That rules out stock shots of famous landmarks with crowds, sports events, celebrities, recognisable shop fronts and products with visible logos, unless the licence clearly allows commercial use.

Model and property releases protect you

A model release is a form signed by a person in a photo giving permission for their image to be used commercially. A property release does the same for private buildings, artwork and some locations. When you use a photo of a person to promote your business, you’re implying something about that person, so the release matters.

• On paid sites, commercial images of identifiable people normally have releases on file. Check the image details if you’re unsure.
• On free sites, releases aren’t always collected, so avoid using identifiable faces in ads or in anything that suggests the person uses or recommends your product.
• Never put words in a stock model’s mouth. Pairing a stock face with a quote or review makes it look like a real customer said it. That’s misleading, and it’s one of the fastest ways to lose trust.
• Be careful with sensitive topics. Many licences restrict using people in contexts such as health conditions, politics or anything that could be seen as negative about them.

Customise stock so it looks like yours

Once the licence is sorted, the next problem with stock photos for social media is that they look like stock. The handshake in the boardroom and the group of colleagues laughing at a laptop have been seen thousands of times. A few habits make a real difference.

Choose better images in the first place

• Search with specific words, such as “hands planting seedlings in raised bed” rather than “gardening”.
• Look past the first page of results, where the most downloaded images live.
• Pick natural light, real-looking settings and candid moments over posed, glossy shots.
• Use reverse image search on a photo you like to see how widely it’s already used.

Make it match your brand

• Apply the same crop, colour grade or filter to every stock image so they sit together on your grid.
• Add your brand colours, fonts and logo in a consistent template.
• Use stock as a background for text, tips or quotes rather than as the whole message.
• Crop tightly to focus on hands, textures or details, which feel less generic than full scenes.
• Combine stock with your own photos in carousels so it supports rather than replaces real content.

Check the licence allows modification before you edit. Most royalty-free licences do, but editorial images generally don’t.

Some posts need real photos

Stock works for illustrating ideas. It doesn’t work for showing what you actually do. People follow small businesses because they want to see the real team, the real premises and the real work. A stock photo of a smiling plumber will never do the job of a quick phone photo of your own van outside a happy customer’s house (with their permission).

We’d always use real photos or video for:

• Your team, your premises and your products.
• Before and after shots, case studies and finished projects.
• Reviews and testimonials.
• Events, launches and behind the scenes content.
• Anything that implies “this is us”.

A good mix for most of the small businesses we work with is mainly real content, with stock filling the gaps for educational posts, seasonal graphics and topics that are hard to photograph. If your feed is mostly stock, it’s usually a sign you need a shoot. Even a half day of professional photography or filming short videos for your channels can give you months of original content.

Frequently asked questions

What is stock photos, in simple terms?

Stock photos are existing images held in an online library that you can license for your own use, instead of commissioning a photographer. Some libraries are free and some charge per image or by subscription.

Do I need to credit free stock photos?

Unsplash and Pexels say credit isn’t required, though photographers appreciate it. Creative Commons images with “BY” in the licence do require a credit. Always check the specific licence.

Can I use stock photos in Facebook and Instagram ads?

Usually yes, as long as the licence allows commercial use and the image isn’t marked editorial only. For ads featuring people, a paid library with model releases is the safer choice.

What happens if I use a photo without a licence?

The copyright owner can ask you to remove it and pay a fee for the use, and can take legal action if you don’t. Removing the post afterwards doesn’t cancel the earlier use.
