Forum itself needs to enable image uploading feature so that we will not depend on any third party before we can upload image and also that there will not be any issue like thus that we should fix anything.
What about this legendary member Rath_ for his helpful posts on lightning network.
Tagging alone will not solve this problem and there are people who would be tagged but will not still respond to it as it might not be their priority for months even years as our focuses and commitments vary daily.
There are some that have a very good topic with images that would be absent for only God knows when as well, which is why I believe that the error shouldn't have happened in the first place instead of calling the attention of those who had forgotten they've even written a post to come back to it.
Personally, I will try the fixing advice of OP in my spare time, but my hope is that this will not persist as other sites are being threatened too. Some are now off and on with their images here, who knows what will happen soon again? Will users continue to be fixing and fixing?
