For what it's worth, the original member told me to size my work to 512 kb or less, so I do.
think you mean 512 pixels...it is the pixel dimension that keeps an image free of magnification.
Probably so, but
Toulouse told me 512 kb and that works for me. Sorry I'm not up to correct terminology.
google can relate what a kilobyte is...pixel too. they are two entirely different things.
