Not to sound like an idiot, but I have no idea how to use it...

It's really simple, actually!
1) Download that file
2) Unzip it with WinRAR
3) Copy all of the folder's files and paste them into the folder you have your icons located.
4) Open the file named 'process.bat,' a DOS window will pop up and ask for a username and password.
5) Enter your username and password, and one-by-one, your icons will be uploaded to the entered username. The DOS window will close on its own, signalling when it's finished.

Hope this helped!

you = my favorite person ever
...even though I did just spend a half hour uploading icons
xD

bwh? i did what you said, putting it in, and the DOS window said it was uploading and then it closed...

except the icons arent there...?
confuzzled.

All right, new plan! :)

Download this file and follow the same instructions as above. The 'process.bat' file will be named 'upl.bat' instead. Let me know how it works out for you!

nope. maybe i'm doing it wrong?

Totes. I don't know why it doesn't work for anyone else.

DON'T QUESTION THINGS LIKE THIS. Conundrums give me headaches. And then Benedict makes that face^

Aww his chin is so narrow. (/too lazy to switch journals)

Brie, is there any chance you're operating on Vista?

Or you can unzip it with Winzip!
