Is anyone else having trouble loading images the past few weeks?
I usually use imgbb.com for hosting images, and lately I've noticed the "Bitcointalk.org Image Proxy: Invalid Image" warning pop up frequently. The problem is inconsistent, sometimes the image is displayed fine, other times the image won't load.
Should I not be using imgbb.com, or is there something else going on?
Same here the problem was there from past two days but some images were visible also so didn't understand what's going on and bumped into this thread and came to know you also facing the same problem.I am also using imgbb for uploading any photos from long time and only once this issue was there but now again facing it.

Maybe you're right, but in this case I think the problem is different. Do you know what size the BestChange avatar file I'm using is? It's only 16kb, but if I host the image using imgbb then the image is invalid [proxi invalid image]. So the problem is not all about the image size, but the problem is with the image hosting site imgbb which may not work well in furum now. But when I use imgur and postimage, the images are hosting well because so far both sites are working fine.
Yeah there was issue at the image hosting site only and usually this outage is rare to be there but there could be some problems and resizing it won't matter.In my case I have adjusted the size of images multiple times with width, height adjustment so at the end embedded it with [url] tags to make it clickable in case members can check it by clicking on the invalid image also.
But don't think so the issue have been resolved as my above image is still not visible and showing the same invalid message so i think it needs to be resolved.
I think postingimages.org is solution to it so thanks for letting us know about it.
