Hobby, Photobucket, stated they would no longer allow "third party " posting unless you paid, it was nothing to do with people deleting their own photos.Although your photos are displaying (and I notice they are all now right way up) many are still not . Where Photobucket has been used in the past, if some of those photos are currently unavailable, a simple explanation might be that the people who provided links in their forum postings to those photos subsequently deleted the photos from Photobucket.
Hmmm.I did try posting one just to kick things off but it was too big. What size can it be?
I referred to this in the Forum Issues & Feeback section.Hmmm.
Good question and unfortunately I don't have an answer.
I just submitted a picture to see if any information came to light, the picture was loading until the error message to say that the picture was too big.
No other information was given.
I'd suggest cropping your picture as much as possible without losing what you want to show and using trial and error.
