My photo archive tells me that .jpg and .bmp files are unsupported and to contact ChrisW if I think they should be. Any ideas anybody? The pictures already in there are all .jpg's

Get that in firefox sometimes. Tried loggin out and loggin back in? It works for me.

I'll have a go. I was doing it in firefox as well.

It works in IE, I'll still use firefox for browsing though.
