Here you go Staby_ this is the link to the Dorling Kindersly stock library. On the whole I like to do my own photography for textures (it means i can determine the shots and do close ups on detail) but we don't have crocs in the UK and I wouldn't want to get that close! The image I used is a Nile Crocodile and you should find it if you search with that.
