Images -handling could be better 1 + 2

1.It would be more comfortable to integrate an "Image-management". When I want to change the header/front image I have to load up a new image. The old one is hold in the images-directory. If I get new Image and load it up, and later I want to chnage to the older one I can not use it or search for it. the picture-grave grows. OK I can delete them with FTP. Is there planned to make it more comfortabel?
2. I suggest an additional line for pictures - naming (explanation) in the photo-gallery
