Image testing
Lots of problems with image cards:
When i edit an image card and try to re-upload the same image (with the same name), the new image is not uploaded.
This isn't exactly a bug, nor is it particular to images, but it is odd. When i click on "Add blah" (an included but nonexistent card) and the create interface comes up, if i double click on the title, the slot becomes a regular card-editing interface - i.e., it creates the card, and now i can edit type, etc. (this is actually very convenient imho, but may betray something buggy going on?
