Quote from SeerahI assume you'll need to create a mini-addon for your textures folder. If you do not know how to create a TOC file...
1. Open Notepad, Wordpad, whatever.
2. Copy in the following:
3. In the "Save" window, save the file to the texture folder with the exact same name as the folder. Give it the file extension of .toc - so if your folder is named MyTextureFolder, your TOC file will be named MyTextureFolder.toc ***Note: depending on the editor you use, you may need to set it to "All Files (*.*)" in its extension drop down first.
4. Log into the game - you should see your "addon" listed in the AddOns menu at the character select screen. (If you don't see it, make sure that you were fully exited out of the game when creating it, and that the TOC file name matches the folder name - yes, it's case-sensitive.)
As long as your "addon" is enabled, the game should load your textures. /edit: this is all assumption - I use SharedMedia and MyMedia for my textures.
