Doesn't this site still have a storage limit per user?
Also, using jpg compression with paint.net (<---program, not website) or other editing program will save storage is you have a limit.
Google photos, no limit
Imgur, no limit
Flickr, no limit with Flickr you can upload full size, then choose the display size from the share menu.
Postimage had no limit last time I checked, but not sure if it is still the same.
The photobucket extension has to do a little work to get the photos and is slower loading them, BUT you can still see them without having the admin edit all your links.
Edit: IF you add the extension, you can leave it disabled until you want to see someones blocked PB links.
You can sit back in a Lazy Boy and watch TV OR get on a motorcycle seat and watch the world go by.
Google Photos............Flickr Photos ...............
