The rules, very clear:
+ Comment if taking (no matter if you take something in each entry, I promise I won't get angry for excesive comments ;), exactlly the opposite).
+ Credit if using (put the following in your user image comment: by <*lj*user*="frienger*_*box"*>, without *).
+ No hotlinking, save everything in your own server, don't have one? Check
Photobucket,
Imageshack or
Tinypic.
+ No editing, REMEMBER! Textless icons are NOT BASES.
+ Don't claim them as yours! Even if I made them for you.
That's it, enjoy :)
