Dont know anything about PhotoStudio, but I would look under the "Preferences" section, to see if there is a percentage adjustment for when you save as a jpg. BUT BE WARNED: when you change this setting, it will save EVERY picture at that setting, SO BE SURE TO SET IT BACK TO 100% FOR OTHER SAVE PURPOSES. You dont want to be saving at 60% for a photo that you will want to print.
You might want to check nonags.com for a freeware imageviewer that can save jpgs at different quality levels. Then use that progam as a dedicated "Saving" program
One that I use is Polyview (www.polyview.com
) - $30.00 american, and a very full featured viewer.
Good luck,
