Photo won't upload to Craigslist from Mac

Hello,

I looked high and low for a solution to this problem, didn't find it, then figured it out so I thought I'd add it:

When I try to load an image from my Mac to my Craigslist listing, nothing happens. The image doesn't load and there's no error message. Doesn't matter which version of the image loader I used, just didn't work. Also didn't matter which browser I used (Safari or FireFox), so I figured it must be the image.

Apple changed photo file types to the new HEIC type, which has a lot of merits, but not everyone is on board (looking at you Craig). If you convert your photos to a .jpg file type, viola, Craig is happy and your image loads to your posting.

Here's the instructions I followed to do so: https://www.howtogeek.com/398927/how-to-convert-heic-images-to-jpg-on-a-mac-the-easy-way/
