i'm assuming to use as toolbar icons...

Right click on adium and go- show package contents

Click on contents, then resources

Inside resources there will be 3 files, adium.png, adiumOffline.png, and adiumRed.png you will be replacing these files.

Go into the folder that you downloaded and choose the images you want to replace. Rename these images that you are going to put into adium with whichever name is needed. ie: if you want the imperial symbol to show in the status bar when you have unread messages change the name form imperial.png to adiumRed.png and drag it into theresources folder. Click replace. You will probably want to make a back of the original .png if you ever want to revert.

sorry, sorry... I forgot and loaded my *incorrect* version.... you see, there were two different ones....
so, here's the corrected one, and thanks to jomatotu.

i actually liked that one. it;s like the one about the salesman who boasts that his vacuum claner will cut your household work in half, and the lady says, great i'll take two of them.

ya know, i'd love to translate this one too, but in english, it just aint that funny!

keep it up, dude

ok, the english version is called "unthinkable questions" and is pending....
it includes a few (three) of my own lines, such as "did adam and eve have belly buttons?"

and, uh, you are welcome for the entertainment, tobias.... schlumpf my eye... ;)
