If it is downloaded, it generally comes in jpg which is nice for storage, but large files are unstable in an "as is" form... Because of the heavy "parsing of data", the least little screwup renders the file unrecoverable... I find increased stability through the use of Graphic Converter (it accesses these "raw" files far more easily and trouble free, especially large jpg files), and doing a "Save" to give the file a picture icon renders the file far more stable... If the file is to be manipulated, it MUST be from then on stored in a larger file format to retain detail... TIFF is Ok, but I prefer PIC (Macintosh) so that I can scan the library with one of a number of programs that don't recognise TIFF PowerPC
