i dont use it for images but for all my audio i use catbox.moe, its reliable enough
I resize everything to keep my file sizes small, averaging about 200kB per image, and just host them on Neocities. Makes organising my files a lot more easier. So far i'm only using 5% of my 1GB limit after almost of year, so it's going to last for a while.
I use catbox.moe; it automatically generates thumbnails which is very helpful for me.
i resize my images and host them on neocities like @murid , and i'm still only using less than 10% of the 1GB
I optimize my images on shortpixel.com, with the "glossy" option (best for art) and host them here. I'm using 1.8% of my 1GB so far.
I recommend maintaining local versions of everything then figuring this out only when you hit the limit :p the cost-benefit of the effort of many solutions isn't there until you're at *least* at that much
I basically want this place to be My Internet Home and sometimes you have to spring clean :3c
