Please describe the problem:
There are two possibilities to resize / scale an image with gThumb:

1. you can use the option "Image > Resize". With this function I didn't have any problems but unfortunately this function works only for one file and not for resizing several images at the same time.

2. you can use the the option "Tools > Scale images". This woks for several images at the same time but this function includes two bugs: Firstly the "keep aspect ratio" option doesn't work (with "Image > Resize" it works): When I vary the width value, the height value doesn't adjust to the width value. Secondly the exif / metadata gets lost when using this function.
