Re: [EP-tech] File Icons

Hi John,

Thank you for the guidance.

I've spent a couple of hours today looking through everything and not

It turns out the imagemagick isn't installed. When I do:

"which convert"

I get nothing! A bit embarrassing that I didn't check this earlier, but
there we are.

Thanks again for your help,
James
