I'm currently setting JPEG quality to 85%, hence the large file sizes.
Normally, I'd be looking for better quality and file sizes about 70% of
their current size. Some of the originals are scanned directly from the
painting, which yields very high quality, some are taken with a digital
camera (I could live with poorer quality on these).
I'm using some functions I found in 'PHP and MySQL web development' with
some modifications, so JPEGs are generated from uploaded files and stored on
the server through an HTML form interface. Here's the core bit of the code:
$src = ImageCreateFromJPEG($image);
$dst = ImageCreate($tn_width,$tn_height);
ImageCopyResized($dst, $src, 0, 0, 0, 0,
ImageJpeg($dst, $path, $compression); //compression set to 85 here.

They looked ok to me, but I don't know what the orginals looked like.
But the problem might be that your JPeg quality is set lower than you would
like. You can increase it be setting a parameter in ImageJPEG() or most
likly whatever function you are using
