Stripping the thumbnails from EXIF

[ATJ]

Does anyone know a way to strip the EXIF thumbnail from JPEG but still preserve the other information?

When I upload images to my website, I try to keep the size small (around 70K) so that people on dialup are not pissed off. I use PaintShopPro which I generally like although version 8.00 has a few bugs. One of the "good" bugs, however, is that it stores the thumbnail as a JPEG, and so it only a few K. When I upgraded to 8.10 it fixed many of the bugs, but changed the EXIF thumbnail to a BMP which can be as much as 50K. I ended up going back to PSP 8.00 as I hated wasting 50K+ and losing quality.

Are there any tools that can manipulate the EXIF data and either delete the thumbnail or convert it to JPEG?

I use jhead to automate removing thumbnails and/or exif data. It can also perform automatic lossless rotate on jpegs (with the help of jpegtran) to get them the right way up.
