Brian,
what are the size of your pictures before you edit them? Are these image (sizes) what you have been using on MSW?
I am sure you know this, but just in case.
You know there are two sizes: The file size of the data like 150kb, or 2Mb. Then you have the width and height size.
At this time, both of these values work hand in hand on SOS. (as I have limitations set up). However, I would get an idea of what you have been working with on MSW.
I also prefer to use a photo image hosting like photobucket.com as you are not constrained too much.
Thanks
Donnie
