Image Quality

Hi,

I would be very grateful if anyone could help me with my questions. A while back I took a Photoshop class and remember a lesson on where you could select a region of an image and save it for the web with a high quality and select another region of the same image and save it for the web with a low quality, so that the focal point was saved with a high quality and the background was saved with a low quality. I have no idea where my notes are from this class and can not remember at all how to do this. Can anyone direct me to a tutorial about this?

Thanks,

Did you use the "slice tool", and save for "web and devices"?

I can tell you how I do it.
Select the first (high quality) region.
Do this sequence of keystrokes:
Ctrl+Shift+C (copy merged)
Ctrl+N (new document)
Enter (...)
Ctrl+V (paste)
Ctrl+C+Shift+Alt (Save for web & devices)
Choose your "high quality settings", save close the document created, don't need to save.

Do the same for the background, but this time choose low quality settings.
