Is there a way to make a max image size? I have a site where people to upload photos.... I don't want the photos larger than 400x400 - but if someone uploads a phot thats a 100x100, I don't want it to be enlarged to 400x400 (Like what height="" width="" does). Is there a way to keep it where it resizes it if's it's larger than 400x400, but it doesn't if it's smaller? Thanks!
