Scam/Vanity Publishing!

When i get bored i google photo competitions and enter some photos, so i don't really know where all my photos are, one place has sent me a letter saying that my photo of 'Smiling Frog'

has made it to semi-final status, and will be in the running for $1000 prize.. but i was a little suspicious so i googled 'International Library of Photography', and they don't seem to have a good reputation, apparently your photo will only be published if you purchase a book, so beware!!
