Well, UncleCheese

You DOM module/ swfupload module have been greater helpers for me as always..
Well, i have just encounter a problem may need some suggestion.

Well, i am building a relatively big site with different user group and security permission.

I have created the ImageDataobjectManger for Carimages on my VehicleEntry Pagetype.

Here is the problem:

For normal administrator (Default Admin)->which has the [Full administrative rights]. everything works fine.

Well, for the content authors-> we limit them only can access the Page CMS Session and also give themall view any page,Edit any page.

Problem: the content authors cannot delete Image from ImageDataobjectManager.(no rubbish bin icon on the right-hand bottom).

The interesting parts:
I have changed the ImageDataObjectManager to DataObjectManager, it can be deleted okay by clicking on the "red-cross" button using content author login.

any ideas of whats going wrong here? Or any one could point a hint here?!

Thanks, Alex
