title: Extract images files from .git repository
body: <p>Is there a way to view and extract all the images that are in all the commits and all the branches in a git repository?
  for example in a branch i add a image x.jpg and commit it, then i delete that image and add a new one y.jpg and commit it. in the repository still there is info about x.jpg in case i go back to the first commit. i wanna see all the images files in diferents commits and diferents branches. is there a way to do that? without going back to old commits to look files per files.</p>
