The point is to insert some dummy image or images to special page of plugin, and allow user to change it.
I found that is possible to use gpOutput::Get('Extra',$area) on special pages. But I need image on specific place and size.
To achive functionality something like gpOutput::GetImage( $image_path , $html_attributes ) but on special page, allowin user to insert\save images from \data\_uploaded\image folder.
So is there a way to make this image editable field without big headache?
