It seems I can no longer post pictures I have in my imgur account.
regarding this, there was an Issue that happened with imgur last year that left a lot of images posted here in the forum broken so theymos decided going forward images from imgur would not be able to post here.
What is the best way to post pictures these days ?
you can use Talkimg.com, I've been using it since last year and it was created by one of the forum members. you can also use what Cryptogreatdane suggested.
