Imgur, Flickr, Photobucket and Image Shack all rank among the most popular image hosting websites. While there are minor differences between these sites, each one is a reliable image hosting resource.
Imgur is the favorite image hosting resource of many social media websites, particularly Reddit. This is because images can be uploaded to Imgur in a matter of seconds. The website does not even require an account to upload images. Imgur is completely free, and images remain online as long as they receive at least one view every six months. Imgur imposes a maximum file size of 10MB for each upload.
