I work on a lot of images each day. I've noticed that when i have a long list of images.. they all read the same size. Yet I know for a fact that some are 10K .. some are 11K .. some are even 15 K... but my detailed view reads 12K all the way down. In comparing file sizes in a MAC and then take it over to a PC.. the PC sizes are much more accurate than the MAC sizes. Anyone know why this happens?
