At the moment I use Lensdump primarily, now I made my account years ago when it was still free but it no longer is AND you have to pay to use it as a hosting site for your site, I've heard good things about catbox tho! the only downside is that catbox doesn't give you a layout to see all your uploaded files. you gotta make sure you save the links on catbox tho cause once you close that tab that bitch is gone
Catbox works well for me imo. Lets you save files that are up to 200Mb in size. Just know that sometimes they go down for maintainence, the images will temporarily disappear until they're back up.
My assets are your assets, friend. <3
