Sample Images in model pages broken

[secondsabre]

Describe the bug
Seems like a large number of example images on various model pages are broken? The thumbnails show, but the actual full-size images don't load. Not sure if this is tied to an external image host or something, but figured I'd bring it up?

To Reproduce
Example model pages with working images:
https://openmodeldb.info/models/2x-GarfieldJr-span
https://openmodeldb.info/models/2x-90s-cartoon-v1

Example model pages with broken images:
https://openmodeldb.info/models/2x-DigitalPokemon-l
https://openmodeldb.info/models/2x-Where-On-Earth-Upscale-Large
https://openmodeldb.info/models/1x-BW-Denoise
https://openmodeldb.info/models/2x-DBZScanLite
http://openmodeldb.info/models/1x-AnimeUndeint-Compact
https://openmodeldb.info/models/2x-UniScale-CartoonRestore-lite
(and lots of others)

Expected behavior
Sample images should load properly.
