Marking objects from view for later use
This sounds like a perfect job for Flag module.

From the module description:


  Flag is a flexible flagging system that is completely customizable by
  the administrator. Using this module, the site administrator can
  provide any number of flags for nodes, comments, or users. Some
  possibilities include bookmarks, marking important, friends, or flag
  as offensive. With extensive views integration, you can create custom
  lists of popular content or keep tabs on important content.


For your use case, I would create a new flag for your image content type. Add the flag operation to your current views of images. Create a new view that uses that flag as a filter.
