Stop using Google image search. Using those images is often illegal and they are not the best images anyway.
Here are a dozen sites that are better and legal.
1. Stock Exchange
Of all of the stock photo sites on the web sxc.hu is the best. It has high quality free stock photos. But be careful. The first row of photos cost money. Clicking on them will take you to a different site where you have to pay. Most of the photos we use here at AuthorTechTips.com come from sxc.hu.
2. Flickr Creative Commons
Every Stock Photo searches several other stock image sites for you. It does not filter offensive images, so use with caution.
Morgue File has many photos that you are free to use commercially without attributing the photographer. The photos are mostly snapshots and not true stock photos.
Not only does Free Stock Photos have some great nature photos it also has a list of over a dozen other free stock photo sources.
IconsPedia has the best selection of free icons. If you want to add a cool Twitter Bird to your website this is the first place to look.
If you need biblical photos BiblePlaces.com is a great place to start.
I’m not sure how this happened but if the U.S. government takes a photo they often release it into the public domain. If you want high quality technology or space photos you can’t do much better than NASA.
StockVault has 13,000+ high quality stock photos. The photos are high quality but low selection. The site does not offer safe search so use at your own risk.
FreePhotosbank has a lame selection of mediocre photos.
If you want vintage photos Historical Stock Photos is the site for you. Don’t expect much color here.
