Legal
Can I use images I found on Google on my website?
No. Google Images is a search index, not a licence source — almost everything in it is copyrighted by someone. Using an image without permission exposes you to a demand for damages, and specialist firms scan the web specifically to find unlicensed use.
Where images can lawfully come from
- Photographs you took yourself, which are also the most persuasive
- Stock libraries where you hold a licence covering commercial web use
- Free stock sites, subject to their licence terms — read them, they differ
- Public domain or Creative Commons work, with attribution where required
- Images supplied by a client or manufacturer, with permission in writing
What "found on Google" typically costs
A demand letter for a single photograph commonly asks for several hundred pounds or dollars, sometimes considerably more, and removing the image afterwards does not extinguish the claim for the period it was published. It is one of the cheapest risks to avoid and one of the most frequently taken.
The practical position for a small site
Use your own photographs wherever the subject is your own work — they perform better commercially than stock imagery anyway. Where you need generic imagery, keep the licence receipt with the project files so you can evidence it later.
The longer version
This answer is deliberately short. If you want the full treatment, Image SEO: findable images that do not wreck your page speed covers it in about 3 minutes — free, ungated, written from client work.
