I have just attempted to upload a JPEG file to the galleries. I failed and a message told me that the format was not yet supported. The picture is JPEG and has been reduced in size.

Have you tried using photobucket? I don't, but have seen a few threads where people say it's easier

Since we moved servers we seem to be having issues with .JPEG files. I managed to upload a sample by changing the file name to .jpg but it hasn't worked for others.
We are aware of it but it won't be getting cured any time soon i'm afraid.

We are looking into new forum software for later this year so hopefully that will cure a few bugs, the version we are running is a bit old hat now.

As pointed out the best way is to use photobucket or similar for now.

Thank's for the reply, if I was posting onto the forum I'd use PB. I'll wait and hope that sometime soon the problem will be sorted.
