So you're saying that they gave you a picture and you want it on your computer with the same quality?
Just right click it and say "Save Picture As" (In IE) and "Save image" (In Opera - I don't have Firefox) and choose the folder you want to save it in.
Then you can probably go to upload it and display it on your own.
If you do it that way, I'm sure the quality and dimensions will stay the same, no problemo.
I
think that's what you wanted. I could have interpreted your question entirely wrong, so if I did - sorry.
