Seems to be more than a few folks who click on a thumb manually who
dont get the full image - consider it dead
Thats not always the case
Example on imagebam
Old gallery from 2011 - most pics wouldnt open from vef post in chrome
until I entered the gallery - top right on the image host and selected a pic

Download managers will miss pics that are alive
Visiting an imagehost gallery link before downloading might help lessen this
The one area it wont help is the truly dead - Imagebam has 4 servers with issues
101 the main one
Imagevenue and its 404 thumbs or thumbs that lead to image not on server are dead
