Setterguy, I'm not sure if the forum bug is causing this or if the direct links you put in your post to IMGUR are not quite correct. When I click on those links in your post they do come up on the IMGUR page but they do not embed in our post.

For now the workaround is a bit tedious.
1. You use the attachment manager to attach your pictures to your post. They do not show up in the post but as attachments under your post.
2. If you want to manually embed them back in you go back to your post on the forum, click on the first attached file which will pull it up in a new window.
3. Copy that address of that pulled up file.
4. Go back to your original post, edit it, use the picture attachment icon in the 'Full Editor' and click the picture. Paste the full address from step 3 into that box.

Do that again for the other 2 attachments step by step. Now all 3 will embed.

You can play with the link you used from Imgur and see if editing that or using a different way to link it will embed it. With Photobucket there were several ways to copy the link (direct, email, HTML etc) so maybe IMGUR has the same catch to get it to embed directly.
