hey andrew, you might want to check the forum rules for posting requests. You must meet them before your requests will be filled. As for the folders, do a little seaching on the site and you'll find them.
I'll help ya this time though.
At the top of this page, move your mouse over " database " then click on the word " database " in the menu. Once it loads click on the Graphics link at the bottom. Then under there you will see a list of posts with various images that you are free to use.
Or click this link to take you there directly.
