Since I'm trying to please a likeable curmudgeon who insists on using dial up I've been trying to figure out how to reduce my pic file sizes without downloading special software and spending a bunch of money on high priced software. I use the IBOOK G4. Select pics in IPHOTO Go to SHARE and select EXPORT You will get a window in which you change the resolution to 640 by 480 EXPORT to desktop with new file name OPEN pics from new file. Should open in PREVIEW Select SAVE AS in FILE You will get a window in which you can change the quality. I reduced mine way down and the quality seems fine. Save and replace the pic. I'm an idiot so their may be a better way.
