Attached are the icons converted using imagemagick, converted to 500x500.

I used a command prompt command, it took about 30 seconds to convert all images:
for %I in ( *.png ) do magick "%I" -set filename: "small_%t" -resize 25% "%[filename:].png"

You could create a batch file to do this (double the % symbols).

Yes, you need to have imagemagick installed, but it's usefulness far outweigh the inconvenience of installing such a powerful tool.

That looks like a good solution if the user prefers a GUI interface :thumbup:

I am "old school", so black command boxes are what I grew up with :sly:

Some people are not as comfortable using command prompts, so having choices is a good thing. 8-)

Absolutely. I like ImageMagick a lot, although I have to say that the documentation for it is... horrifying...

That was quite the chronicle that went down while I was sleeping!

I had installed and tried to use imagemagick myself, but the command that was shown on the example page that ET linked was invalid and I didn't have the necessary knowledge to be able to figure out the problem. So, thanks again!

I'll try these out when I get home and get back to you.
