Has there been a radical change to how JPEGS are compressed? For several years I have been producing thumbnail images (240 px wide by 150 px high) of product photos. Under XP with CS2 the files were averaging around 19Kb with quality setting at 7. In my Vista/CS3 environment the same image, saved at the same quality and format is 40Kb. This doubling is fairly consistent and can be replicated. The only thing I can imagine might cause this is if JPEG now have a larger metadata portion than before. Anyone else encountered this?

Buku, thanks for the advice. However, although saving for web does indeed result in a smaller file size, it doesn’t answer why the files have suddenly started getting bigger.

Stuart,

Maybe now you include a profile?

About to say the same thing, including profiles in (particularly) small Jpgs will bloat the size dramatically. it might be on by default now.
