Issues uploading photos

[GoldenSnitch]

I go to MyMumsnet and Upload new photo, browse for one then hit upload - at which point I get a new blank screen with "http://www.mumsnet.com/member/MemberPage" as the address.

Refreshing the screen brings up the same page.

If I go back into MyMumsnet, the photo isn't there.

Please fix it, I want to show the ladies on the December 09 thread my smiley baby
