How to
Edit a page
Add some text with the inline editor
Add a picture from the hard drive (I put in copy the picture I used)
Save

Actual Behavior
The picture is not displayed, a white square with a red cross is displayed instead of it.

Expected Behavior
The picture is displayed (size and location should be fine)

Note
I did the security modification as explained in the user manual for IE7 (see in attachment)
A picture inserted in the structured content (from the hard drive) is displaying well.
If I open it again I've got the white square with red cross.
