edeting uplode zone

Hello!

I need a halp with customazing upload zone.

Is it possible to set the frame to be selected for upload zone in which the inner part of the frame is the upload zone, and the outer part of the frame remains visible, the image does not cover it all over? Such an image frame must be able to move the frame itself and replace the images in the upload zone. In the attachment is an image showing the upload zone as a frame, but when I enter the image it covers the frame completely.

Any solutions? Is it possible to determine the margins of an element that is both an image carrier and an element at the same time?

Thanks!
