The only way I have found is to create a free account on an image hosting site and then post references to uploaded images. It’s a pain, and only reserved for posts that demand images to make a point. I am guessing they don’t want to pay for storage costs for all the images that would get posted, not to mention policing them.
Why no pics on A’gon Forum?
Unless I’m missing something, it is not possible to post pics on the Forum. Other sites like What’s Best Forum allow this and it is very useful.
I sent in a feature request. Please consider doing the same if you’d like this functionality.
A’gons’s customer support contact page has such a link. Should be a simple improvement to the site.
