[Evergreen-general] Cover Image uploader

[Jason Etheridge]

Hi Samantha,

Web browsers can be particularly aggressive with caching images.  If
you upload an image on one machine, does it show up instantly on a
different machine that hasn't pulled up that record recently?  If so,
then it's likely that patrons in general are seeing the new image.

As described by one staff member struggling with it: "If it works, it works instantly. Clear your cache and look quickly; a massively compressed version of it will be there. Shortly thereafter, the image vanishes from the server and you're back to gray squares."

Sometimes one that was visible instantly no longer shows up for them later. Sometimes a hard refresh will force the image to show up, sometimes it doesn't. Sometimes it takes more than 24 hours for the image to be visible.
