I see you do not compress the .jpg's. In my opinion nice, but although when you only publishing your own retouched remastered the limit would be quick reached.
MediaFire, GoogleDrive and all best cloud services or image services have most a limit of 10GB, the only platform so far with no limit is ImgBB. Know too less about the feature set there.

Here on the forum I have to reduce the file weight to 1MB, otherwise it will not upload or it will reduce the file size in pixels.

By the way, I found confirmation of this in your link. This forum uses imgur.com as a repository.
