The ‘But it’s on the Internet, so it’s free’ questions always come up. The fact it’s on the internet doesn’t mean it’s free, or that you can use it any way you please.
“There's a simple solution: search for images "licensed for reuse" -- images that you may legally use. Both Google and Bing may be set to show images with this license. The license exists thanks to Creative Commons, a nonprofit organization founded in 2001. The organization promotes legal sharing of created work, and the creators specify reuse terms and conditions.” - TechRepublic
There’s a good way to search out the ones which are free to use, free to use and modify…well, there are 6 licenses with increasing restrictions on usage… is with Google Apps and CreativeCommons.
On CreativeCommons, the least restrictive is “Free to use with attribution”, the most requires attribution and prohibit both the creation of derivative works and commercial use, and you can learn about them here: https://creativecommons.org/licenses/
There’s a really good article about it here: http://www.techrepublic.com/article/four-ways-to-find-free-images-to-use-legally-with-google-apps/#ftag=RSS56d97e7
This is just to help you in your search for usable images. If you upload images and artwork to CreativeCommons, you’ll even run into their licensing tool to help you create the proper licenses for your work.
WC enforces the policy that IP (intellectual property) is sacrosanct…if you’re in doubt about an image, just ask Jafo or the other Gallery Mods. If you use an image not of your own making, you have to have the license included in the zip along with the image/s, unless it’s fan art. Nothing new about that.
I hope the Gallery Moderators will chime in. I’m only bringing you awareness of a tool available to you in your searches, and simplifying (hell, over simplifying) the rules of the game.
I’ve also tried to centralize some tips and rules governing uploads/moderation, etc. here:
