Hi, I'm pretty new to Xenforo and to creating forums in general, so I'm starting on the ground floor here. I've never used sprites for anything at all and I'm trying to add custom node icons and smilies. I have downloaded an Android smiley pack, but when I unzipped it they are all separate pics. Should these be added to the sprite sheet I see in my xenforo default directory, or added separately? How the heck do I make a sprite sheet? (I have a good grasp of Photoshop, but never have heard of sprites). Also, the node icons...can I just open one of the node sprite sheets in Photoshop, cut out the old icons and paste mine in, or is there more that goes into creating the sprite? Any help, tips, or links would be greatly appreciated, thanks.
