hi,
I am no genius...lol...
there is a difference between editing in 8 or 16 bits pixal depth and working with a image that a color depth of 8 or 16 or 24 bits, etc... there really 2 different things....

when you save you image as a jpg... the standard jpg format is that it is saved in 24 bit color!! so there should be no issue there... as far as your picture .. it will be 24 bit color!

note: png , when you save in that format, you do have a choice of 8 or 24 bit color depth.....

now your image.. you can go ahead crop your image to that 600x600 and do whatever editing.... then i suggest you choose "save for the web" from your file menu, now there you can then adjust the quality/compression of your jpg file to where you can get the file size you want!! and that it..

ok on the 24 bit color which also is called true color... does consist of 8 bit assigned to blue, 8 bits assigned to geen, 8 bit assigned to red Answered Nov, 27 2010

Save it as a BMP file. This format allows for 24 bit, and its an option when you "save as" to this file type. A 24 bit requirement isn't uncommon, its the standard image type in windows and some other softwares. Answered Mar, 06 2011
