Sometimes i look at a thread with 100 or more pages, is there a way to easy found out if somebody already posted the same picture that i would like to upload as contribution ?

Try doing a Google Image Search search by image. They have a lot of hits back to OCC.

The image search works really well. So many folks change the names of the file when they save them. Seriously, how many jpg's do you have that are named "1"? The image search will usually find the original, even if the file name has been changed.
