Where are folks hosting images they want to post to kbin? Uploading images never works for me, and using imgur link gets no thumbnail.
My understanding is that the imgur thing is imgur's fault, but until the image upload functionality is working I don't really know what the best choice is.
Do you have ublock Origin, NoScript or something similar installed on your browser? Maybe you have blocked the script that uploads the image or something
I'm also having this issue and have been unable to create new image posts since at least last Thursday. I never notice any issue with the upload dialog, but I always get the "We are working on resolving issues" message once I try to submit my post, and when I check my post history, nothing new come up. Posting from Chrome on Android.
I use IMGBB, been using it for my Friendica as it gives convenient cut and paste BB Code which Friendica can parse. I did test Kbin and found it parses the HTML code they offer... Or at least did when I was testing, let's see, does this work?
