Answer 5

In what format is the picture? If zhpg then 500 KB is really a lot for such a resolution.
Under ubuntu, install the imagemagic package and in the terminal
cd /papka/skartinkami
for file in *.jpg; do convert -quality 60 $file $file; done
All images will be compressed at 60% quality. Make a backup in advance, because after executing this command, all files will be rewritten compressed
