It's not tough to preview and approve or delete. 

Approval display page can be built to show thumbnails (Small/Medium/Big) sizes with optional quantities 50,100,150,200 etc.

You choose your display preference based on your connectivity strength. Select all, Then scan through to see and deselect the bad ones and approve and trash the rest. I think it's worth the trouble.

Let whoever does not want it have the option to activate "Auto Approve"
