Imgur

Imgur is an image sharing community and former image host.
== Vital signs ==
Seems stable for now. Images submitted by free users are deleted after not being accessed for 6 months.
Imgur serves a massive amount of traffic. In 2012 alone, 42 petabytes of data were transferred. Fortunately, the amount of images uploaded is much less, albeit still a lot. In 2012, around 300,000,000 images were uploaded; assuming an average size of 120KB, that's 36TB in one year. As of 2014, there were 650 million images with 1.5 million being added each day according to one source. An analysis in 2015 based on extrapolation from a sample of random image IDs estimated about 2 billion images with a total raw full-resolution image size of 376 TiB.
Imgur was originally created as a gift to the Reddit community because of problems experienced with other image hosting services. It was used extensively on Reddit for many years until Reddit introduced their own native image host (at http://i.redd.it/) in 2016, causing a significant decrease in submissions to Imgur.
In 2018, there were reports that Imgur had started to enforce their terms of service, specifically that using Imgur for image hosting is not permitted and may result in deletion of those images.
In 2021, Imgur was acquired by MediaLab.
In 2023, in a page titled "Imgur Terms of Service Update [April 19, 2023]": "Our new Terms of Service will go into effect on May 15, 2023. We will be focused on removing old, unused, and inactive content that is not tied to a user account from our platform as well as nudity, pornography, & sexually explicit content. You will need to download/save any images that you wish to save if they no longer adhere to these Terms. Most notably, this would include explicit/pornographic content." Like Tumblr, Imgur will remove porn and similar in 2023-05-15; they will also remove "old, unused, and inactive content", which makes Imgur much less of a persistent image host.
On , Imgur started redirecting direct image links to the corresponding page. They had been doing that based on the referrer before already (for hotlinking protection), but since this date, they are also redirecting when no referrer is sent, e.g. because you open an i.imgur.com URL directly in a new tab. The detection seems to be based on the Accept header; if it contains text/html anywhere, regardless of the weight or any prefixes and suffixes, the server returns a redirect.
== Archiving galleries ==
When archiving a larger gallery, eg. https://imgur.com/gallery/PTFfu, a simple ArchiveBot !ao won't do because of the JavaScript "load more" button. However, you can append /zip to the URL to get all pictures in full like so: https://imgur.com/a/PTFfu/zip (old URL format used to be https://imgur.com/gallery/PTFfu/zip).
== Sitemap ==
A sitemap from May 2017 onwards can be found at https://imgur.com/imgur-assets/sitemap_gallery/gallery_images.xml. This sitemap only covers galleries, i.e. albums shared publicly on the platform.
== Further observations ==
While the Wayback Machine is able to save individual Imgur posts as of 2022, the "trending" section and the home page are not saved properly, as indicated by archives from November and December displaying the same trends on the front page.Imgur (from the Wayback Machine, 1 November 2022) (mirrored)Imgur (from the Wayback Machine, 2 December 2022) (mirrored)
Using Save Page Now alone is not sufficient to archive an image or album/gallery page completely as of early 2023. The created snapshot must also be loaded in a browser to trigger the retrieval and archival of the images themselves via JavaScript. For larger albums, this can often fail on some or all images due to SPN's rate limits, requiring retries.
