I've done this sometimes with hosting images and other large files on a combination of Flickr, Wikimedia Commons, Internet Archive, and Zenodo. Flickr costs money, but it feels like it's worth it given I'm using Netlify and all the others for free.
I know some people use S3 services for hosting images, but then you have to worry about generating your own thumbnails etc. and it's trickier.
