What's the download/IP-Limit on environment-textures? I've downloaded like 10 cloud images at the beginning and now it keeps telling me that I've hit the IP-Limit, although it also says 52/250 photos. :/
Unfortunately, I don't know the exact limits that environment-textures.com have put on the contest account (other than the fact that there are some, for hopefully obvious reasons).
As soon as I get some more info, I'll post it here - and sorry that it's not working out for some people.
