I'm quite happy with everything suggested so far. Whether I load a foto from the gallery here or flickr, it's really not a problem, I've just not used the gallery here yet. Never having won a competition, I can't judge what is possible and what not
As to processing - if none whatsoever is allowed, then there would be no point to shooting in RAW, other than having the original on file for future modification. I think we all do a certain amount of processing, and the person organising the comp for that week can always specify no processing which alters the image drastically if he feels so inclined - as those posted above by Jim and Andy - super shots btw - or HDR or whatever.
IMHO we've always had a good mix of shots - where's Mark BTW? I certainly don't mind keeping that mix.
