discrepancies in image size

i hope this is the right forum.

anyone else notice a discrepancy between the stated image size between their computer and what RFF says it is upon uploading? see attached two screen grabs for the same exact file.

yes, snow leopard. 10.5.8

then how the hell do i figure out how "big" my resize is when uploading to RFF? isn't there some sort of industry standard with this type of thing?

Ha! Funny you should say that. There actually IS a standard. It's a matter of who's standard you believe in.

HDD manufacturers like to use base 10 math, so a gigabyte is calculated as 1,000,000,000 bytes. The confusion arises because computers have always used binary, or base 2 math. That same gigabyte is then calculated as 1,073,741,824 bytes. Add to that the fact that formatting a drive consumes additional space. In the end, that "500GB drive" only gives you 400-and-change GB. Apple even got sued over this nonsense.

More details on this...

Though it seems this changed in SNOW Leopard (10.6.x) whereas you're running the previous, regular Leopard (10.5.x). Perhaps it changed in a subsequent update to make the two behave similarly...

you're making this stuff up, right?

um, you lost me at "base math". thanks for the info though.
