We used to upload images from different sites and include them in topics. During high traffic, images were getting deleted.
Our project is international in nature and broadcasts in a total of 20 languages. We have deployed our image upload system, which is entirely on a CDN infrastructure and has no disk traffic issues. All image files are hosted on the CDN infrastructure. Therefore, even if an image is viewed by 1 million unique people at the same time, there are no slowdowns or loading issues. You can use it on your different sites with peace of mind, without the worry of images being deleted.
Hope it serves the community well.
