Hi, thanks for the advice again!

I have finally managed a way for achieving this optimization. I'm stripping out all of the Profiles from the new image with $image->Strip() and then creating a new IPTC Profile only with the information that I want. The IPTC handling is done with the Image::IPTCInfo module.

This seems to be working quite well since it's reduced thumbnails that weighed 25KB to only 5KB. It takes around 1.5 seconds to process each one, so I guess it's ok.

Thanks again and regards,
Ralph
