E−Hentai Image Viewing Limits

All these information is tested by myself, so they may not correct.

• You have 5000 points every day if you logged in to E-Hentai (typically, vary based on server load)

  Notice that your image limits usage is calculated by your IP, if you are using a public IP, the usage is from all the E-Hentai users who use the same IP with you.

  If you have a Bronze Donation (at least $20), the image limits will count by your account instead of IP. Also you can increase your image limits by donation and buying Hath Perk.

• All the E-Hentai sites use the same image limits system

  E-Hentai, Lofi@E-Hentai and ExHentai use the same image limits system, so the usage of image limits is all of these sites.

• Reaching image viewing page (get image URL) will cost 1 point by default

  When reaching image viewing page (URL looks like this: e-hentai.org/s/[Image ID]/[Gallery ID]-[Page Number]), you will spend 1 point of image limits. Whether the browser fetches the resized image successfully or not, or how many times you fetch the resized image won't affect your image limits.

  In the updates of Mar 03, 2016 and Mar 13, 2016, E-Hentai supported lofi images (low resolution images) and high resolution images, so the cost is also based on image size.

  • Auto (1280x): 1 point (6 points without loading from H@H)
  • 980x: 1 point (6 points without loading from H@H)
  • 780x: 1 point (6 points without loading from H@H)
  • 1600x: 3 points (8 points without loading from H@H)
  • 2400x: 5 points (10 points without loading from H@H)

• Reaching image viewing page with nl parameter will cost more points

  When reaching image viewing page with "nl" parameter (After clicking "Click here if the image fails loading", this parameter will be added. URL looks like this: e-hentai.org/s/[Image ID]/[Gallery ID]-[Page Number]?nl=[NL variable]), the image will be loaded from E-Hentai server instead of H@H network, and it'll cost more points of image limits. Based on your resolution, it'll cost around 6-10 points, see previous section for details.

• Downloading resized image won't cost your viewing limits

  Whether the browser fetches the image successfully or not, or how many times you fetch the image, it won't affect your image limits, it costs only when you're reaching the image page.

• Downloading original image will cost 1 points per 0.1 MB

  When reaching original image 302 redirect page (URL looks like this: e-hentai.org/fullimg.php?gid=[GID]&page=[Page Number]&key=[Key], it's the link of "Download original [X] x [Y] [File Size] source"), you will spend 1 point per 0.1 MB of image limits (since Aug 2019 or earlier. Before that it's 1 point per 0.2 MB, less than 0.2 MB is not counted, and before Oct 2016 or earlier it's fixed at 6 points per image). For example, if the original image is 2 MB, it costs 20 points, 2.1 MB costs 21 points, but 2.05 MB costs 21 points, too. Have a look at this issue to see our tests.

  But only reaching this redirect page will cost your points. That means, reaching real image URL (looks like [Host IP]/ehg/image.php?... or [Host IP]/im/...) won't cost your points. So in E-Hentai Downloader 1.12 1.14, script will fetch image's final URL when failed fetching original image (In old version, script will reach redirect page to retry).

• If it's in "Peak Hours", downloading original images will cost your GPs since 2022-06-06
  If it's in "Peak Hours", downloading original images of 7 30 days earlier galleries will cost your GPs since 2022-06-07
  If it's in "Peak Hours", downloading original images of 90 days earlier galleries will cost your GPs since 2022-11-25

  If you don't have enough limits even outside peak hours, you need to spend GPs, too.

  The GP cost should be around the double of your limit costs, like a 2.05 MB image costs 21 points, at peak hours or you don't have limits, it'll cost around 42 GPs.

  If you're a donator, you'll not being charged by GPs since 2022-06-07.

  In short, if you're not a donator, during weekdays at 14:00-20:00, or from Saturday 14:00 to Sunday 20:00 (in UTC), or not in these ranges but used up image limits, download original images of galleries which is at least 90 days ago, will "prepurchase" 1000 GPs for this and next downloads, until it used up and "prepurchase" again.

  For what is "Peak Hours", see the full update logs from E-Hentai below.

  2022-06-06

  Using the "Download source image" function will now consume GP during peak hours. "Peak hours" for this purpose is (in UTC) weekdays between 14:00 and 20:00, and weekends between Saturday 14:00 until Sunday 20:00. This will also be used outside of peak hours if the image viewing limit is exhausted.

  The GP cost is the same as what it would be for resetting the image limit, and also the same as the archiver cost for including it in an archive for a donator.

  For database health reasons, this function will consume 1000 GP at a time, adding a "hidden" full image quota which is drawn from until it is exhausted.

  2022-06-07

  A couple of minor tweaks to the "Download source image" changes, since it dropped the utilization by a lot more than we needed it to:

  • It no longer applies to galleries posted in the last 7 30 days.

  • It no longer applies for donators.

  2022-11-25

  • One of two new image servers that replace the current oldest image server is now live. (The second one will probably go live in about a month.)

  • Increased the cutoff for how old a gallery has to be before it charges GP for original file downloads during peak hours from 30 days to 90 days.

• Regenerates at a rate of 3 9 points per minute (vary based on server load)

• Your image limits can be seen at https://e-hentai.org/home.php

• You can reset your image limits by paying your GP or credits
