Which photos cannot be used for sale in the UI KIT?

Question

User interface

Will I violate copyright if I use photos randomly taken from the Internet and then sell them in the UI Kit?
For example:
There is a lookbook of clothes that I have shot, can I take these photos and use them in my UI kit and sell them? Or do I need permission to use these pictures?

Answer 1

Google has a setting to search for photos with a specific license. You can also use free photo stocks, here they are all in one heap: allthefreestock.com (I myself prefer visual hunt, also available on this site)
