Crash due to large image file

[lightaffaire]

We generate large collage image files for printing.

thumbgen consistently crashes on a directory containing a 24213x14173 pixel 200Mbyte image. All images are valid jpegs and can be opened and viewed using 'feh'

Setup: AMD 4750G / 32GB RAM / 512GB SSD / 50TB NAS / Fedora 37

Error message:
$ thumbgen -i -r -d /imgs/prn_420x240cm_color

Found 1 files in the directory: /filer/imgs/prn_420x240cm_color
