Determine value of preloading images server side

[haganbmj]

Right now all images are loaded in the dom, which created some issues when I was (trying to) streaming off a gaming store's poor internet.
Images were fetched and loaded on the dashboard side, but the main output had to reload the assets since the browser's didn't share a cache.

The workaround I settled on in the interim was to load any previewed (hovered) image in the background obs-side. It works and it's probably the least intensive way I could come up with on the fly?

The main problem is that scryfall provides half a dozen different image options and preloading all of those doesn't sound beneficial.
