feh can crash the system

[kpcee]

I like to use feh very much but one behaviour is very annoying and can even lead to a system crash. If you open a directory with feh which also contains video files (.mp4, .mkv perhaps others too) the following happens:

If the next file is a video file, it will be loaded into memory completely, no matter how big it is. feh is completely blocked during this time and cannot be terminated, nor the file can be skipped.
Since the file is loaded into memory completely, this can cause a system crash if the video is very large or the memory is low.

The console will then display the error message

feh WARNING: ... - No Imlib2 loader for that file format

I would appreciate it very much if feh would ignore videos in a future version, or at least files above a certain size.

System: Arch Linux
Version: feh 3.3-2

it's a duplicate of #505.

The problem can easily be solved by the following call:
find . -type f -iregex ".*\.\(jpg\|jpeg|bmp|png|pnm|tiff|gif\)$" -size -30M -print0 | xargs -0 feh
