Today I am facing the issue that the images that i upload using
https://imgbb.com/, most of them are not loading and showing this message in red.
Why are you still using other image hosting servers? We do have a dedicated image hosting website which has been working fine and does the job wonderfully. You are aware of that website and still, you are using a third party which makes me question you, why did you create this topic? If you were a newbie I could have given you the solution whereas you are not and it is not that you are not active or do not know about Talkimg.
I would love to hear the reason why you are not using the recommended and dedicated platform for hosting images for BTT.
