In our never-ending quest to tell people about our stuff, we've had to use websites to host images. First, we used Imgur, and that had a bunch of problems. Apparently they will sometimes just block hotlinking for no good reason - apparently especially to sites like DriveThruRPG. That's the main site I need the service for.
Then, I was told Discord could do it. That worked *great* for... about two months. Then Discord removed that functionality. Back to Imgur's awful services.
But today, I found Postimage. No promises as to whether or not it will work forever, but I was actually able to use it the first try.
So that was nice.
Kickstarter is still in its pre-launch phase. Give it a follow!
