I see a number of people worried about hard to use or retired image hosting services... We built halie.com
, it's really easy to use and fast, free. It stays out of your way, no advertising. The platform is built on AWS+EFS+RDS and although it was built as an experiment we have no plans to take it down.
If you store an image permanently you have to put in a valid email and from time to time you get a link you have to click to keep the images from being deleted, after the initial email, depending how how many images you upload, you should only get a reminder about twice a year.
It was built specifically for hosting images so perfect for forums and you get the ability to manipulate the image with hardly any effort, for example if the image is halie.com/abc123.png
you can change the link to something like halie.com/scale/50/abc123.png
and it will scale it down to 50% or whatever you need.
Hope you guys find it useful!
