Excuse my english.

Suggestion 1 :

It would be nice to define a default image for each magazine issue.
For each issue, one image for vertical content,
one image for horizontal content.

so if there are 10 issue,
they will have 10 default images for each horizontal zone
and 10 default image for each vertical zone

the image should be automaticaly apply

Suggestion 2 : url location for content image
have the choice to select an url image loction.
actually the image for content issue should be on localhost.
but how to proceed if all the image are locate for example in a subdomain, or in other webhost..
no solution for the moment.
