I don't know if it has helped but we've given the image hosting a kick, so see if that helps:

Also I tend to externally host my images (on Lensdump, other services are available) which takes the strain off the instances hosting and keeps everything in one, easy to find location. It should, at least, get around any issues like this.

Oh and I also started !photography@feddit.uk if you are interested. I just need to get my arse in gear and post there!
