I would say that you should add content/create of image in Media/Images or in media section. It's also perhaps necessary to add ezoe/relations as well.
Thank you for your answer, unfortunatley it does not work for me.
I have added the permision content create image, and ezoe full access, Also create image on any section...
I can select the image I want to upload, and there is a Location option, if I select Automatic, i get premission denied, but if i select location "this" than I can upload. Problem is on some pages I cannot select "this"... Any idea why this happens?
Hum that's weird. I guess that to be able to select "this", you have to meet the following requirements :
the class of the element you're editing has to be marked as a container
you also need to have the right to create an image object under the object you're editing
and perhaps this works only when you edit an existing objet, not when you're creating one.
On the initial issue, what is the exact message you get when using "Automatic" as location ? By the way, "Automatic" is in fact a value that is computed from the type of file you're uploading and from the rules set in content.ini. So you should also check that the paths set in content.ini/[RelationAssignementSettings]/ClassSpecificAssignement are valid.
