You may encounter the “page not found” or “image not found” imgur.com errors if you are browsing via mobile view. The fix for this is to switch to desktop view on your android device.
If Imgur is not loading or showing “Over Capacity” error, that means Redditors have overloaded Imgur servers. Reddit is the biggest social networking website that uses Imgur for sharing images. Redditors share very interesting images, and that overloads the Imgur servers.
