I have some new actions you might want to review and add.
I don't know enough about pull requests etc so it's just as easy to send a zip file to you.
The one for my camera images is reallllly a personal task. Not sure others would want it.
The edit ico/dll action depends on Greenfish Icon Editor Pro installed in Wine. You'll see in script.

Just noticed the two IDJPG and IDPNG scripts in the zip file need the variable quoted to work with files that have spaces.

for a in *.jpg; do if [ -e "$a" ]; then identify -format %wx%h" %f\n" "$a"; fi; done
for a in *.png; do if [ -e "$a" ]; then identify -format %wx%h" $a\n" "$a"; fi; done
