Feature Request regarding Picture Gallery Front End.

Would it be possible to get:

• a short (content) description with with up to 5 lines (and then "cutted") below the thumbnail(s)
  here:
  and here:

• when clicking on a picture within the album, it would be good to have more information about the picture. Smilar like here:
  http://custom.simplemachines.org/mods/index.php?action=download;mod=473;id=235518;image
  Maybe some EXIF data can be read and displayed?
  And it would be good that pictures can be commented by readers/or those who are allowed...

• when clicking on a picture within the album, it would be good if the full text/description could be displayed below the picture.
  Here I would like to see the text above "Open in a new window":
  

Thank you.
