I try to change the footer of my signature.
I had uploaded a picture before and it worked fine. Now I want to change the picture.
I go to the personal settings and edit the footer. I delete the existing picture and
1. with control V add the new picture or
2. with "add picture" browse it on my PC
In both cases it does upload and shows it correctly. It even tells me it has been updated but when I go out and in again it still shows the old picture.
