Kepfeltoltes.hu is probably the oldest still living and the most popular instant image sharing service in Hungary. Since its start in 2004, it has hosted millions of images. However, the maintainers delete old pictures after an uncertain amount of time.

Vital signs

Technical issues

One can enter an email address and receive information about what they uploaded. This function doesn't seem to be working properly.

Some users have been complaining about the speed and availability of the site, but the writer of these lines hasn't experienced such problems too often.

Administrator activity

No signs on the site, but it is not necessary anyway, it runs on its own. They post messages on their Facebook page rarely, and they reply to mails sometimes with weeks of delay.

Financial status

Operated by ETSz Kft. (reg. nr. 01-09-710373), it has a webhosting service tarhelyem.hu. Seems okay, but the company has just took a big loan, so we should keep an eye on it.

Site structure

Users can select files (up to 20) from their computers and upload them very easily. Then they get the URLs of their pictures, which they can insert to forums, chats or anywhere. Uploaders can decide whether their pictures shall be public, that is, appear on the list of pictures recently uploaded by users (http://kepfeltoltes.hu/public.php?ok=ok&btn_tovabb=Tov%E1bb; NSFW alert!).

Image page URLs are all unique, they are like the following: http://kepfeltoltes.hu/view/YYMMDD/FILENAME_www.kepfeltoltes.hu_.EXT, where YYMMDD is the date in this format, FILENAME is the name of the original file, EXT is the file extension (jpg/jpeg, png and gif files are accepted). The actual image URLs are like http://kepfeltoltes.hu/YYMMDD/FILENAME_www.kepfeltoltes.hu_.EXT, but those are, of course, linked from the image pages. What is not linked on the image page (but is referred to in the code handed out) is the thumbnail version: http://kepfeltoltes.hu/thumb/YYMMDD/FILENAME_www.kepfeltoltes.hu_.EXT

The way the URL is generated prevents others to find the images not made public. Thus, in the following, we talk about public pictures only.

The site lists the last 6000 uploaded public pictures on http://kepfeltoltes.hu/public.php?ok=ok&btn_tovabb=Tov%E1bb. There is no index for older pictures, and, as seen above, they can't be efficiently discovered with brute force.

Content

Although some percent of the image corpus is NSFW content, most of the files are screenshots and photos of objects and people.

Data growth

The number of public pictures grows usually by 3–4 thousand a day; more are uploaded on weekends than on weekdays.

A sampling of ~48,000 pictures from November 2014 gave an average image size (including image page and thumbnail) of 536 KB.

user:bzc6p's index of public images uploaded in year 2015 has 1,175,660 elements (some, up to a few thousand, are missing). It would weigh ~616 GB calculating with the size estimate above.

Data deletion

There is no certain information about the image deletion policy applied by the maintainers. Some people say that pictures may be deleted after some months, however, some testing shows that several years old pictures are still up. It seems to be most probable that they mass-remove older pictures only (that is, several years old ones), probably to free up space. Staff is also willing to remove certain pictures on request (either by the uploader or offended people).

As of December 2014, all images uploaded before July 2010 seem to be gone.

Update: The Grim Reaper sped up in 2015. As of 2016-01-01, images uploaded before August 2013 seem to have been deleted.

Archiving

Since 2014-11-12, user:bzc6p has been exporting a daily index of uploaded pictures. (The last day's image URLs can be parsed from the list of last uploaded images, see above.) He has been downloading the indexed pictures (with a lot of delay, but no hurry) since September 2015.

He had also saved older images discovered on the internet, see below.

Older pictures

One can't find pictures with the site:kepfeltoltes.hu Google search term. One must search for kepfeltoltes links inserted into websites, and copy-paste the links from there, or, write a script that parses them out automatically.

Problem is that Google doesn't show all the results. Not at all. It seems that it leaves out some big websites that have a ton of these links. However, if search is done only for those sites (with site:), they are found.

This has been done for several major Hungarian sites.

Archives

Images from before 2014-11-12, what could be discovered: https://archive.org/details/kepfeltoltes_hu_pre20141112. ~26,000 pictures, along with their corresponding image pages and thumbnails, in 5 batches (WARC files), 12 GiB total.
