No, what you do is highlight everything in the folder you just installed, and copy them. Next, go to the Resource folder and paste them in. A window will pop up saying that a file with the name adium.png (or whatever) already exists, do you wan to replace it? Hit yes. Do that (press yes) for every time it asks you if you want to replace the files. I know, the instructions are unclear! I had trouble with this the first time until I figured it out. =)
