well i have a little problem when i try to add my own ad/sign (via Select URL)... the ad/sign will look like this after ive pressd OK.http://dexu.kuvat.fi/kuvat/TrackMania/tm_ad_problem.jpg
For large signs the size I usually use 280x140 to ensure an instant download, but some trackmakers go as big as 512x256 (It's always 2:1 ratio). Small resolutions don't look that bad in the game. Small signs should have 1/4 of those dimentions.
mine is 500x250.. that is 2:1
but why does it show up like that? or is the pic too large for that sign?
