I had a problem with my hosting company and it looks after they fixed the issue, all of the images on my galleries disappeared.
Images posted since then are showing up fine though.
I FTPed into the directory to look for the images that are missing and they are there. But for some reason the site is wanting to show them with the user's user number added to the beginning of the image name on all of the missing ones.
