  1. First of all, please ask me if you need help, but be sure to read this user manual first and also the wiki if needed. To keep this manual/readme easy to read, a lot of information is placed in the wiki. Most users who have problems with the automated gallery downloads feature simply did not complete the setup according to the instructions.

  2. This is the public version of a private script I wrote for myself over the years. I did a lot of extra work and made this public version just to help others improve their experience on EH. I would be happy if you find my script useful, but otherwise I have nothing to gain from it.

  3. Since this is just a private script I wrote for myself, it naturally does not collect any information from the user and does not do any fishy stuff. The code is self-contained, fully transparent, very readable and well documented, so it should be easy to inspect if you would like to have a look.

  4. I am purely self-taught, so I am not a real programmer and may have limited ability to debug telepathically and fulfil feature requests. Real life constraints also make it difficult for me to work on this script. However, I am quite confident in its quality and readability, since I did spend several years and hundreds of hours on it.

  5. Although I have been using this script for years, it is too big (5,000+ lines of code) for me to test all usage scenarios on all platforms, browsers, userscript engines and EH pages. I know there are a few errors that the script cannot handle, because I cannot even trigger and see them in the first place. Therefore, there might be bugs and you can always submit a report to me to solve any problem you find.

Firstly, regarding compatibility:

  • Greasemonkey is not supported because it is weird these days and breaks some of the features for unknown reasons.
  • The automated gallery downloads feature basically requires Tampermonkey, because it is the only userscript engine that nicely supports
  • Tampermonkey on a Chromium browser is the recommended combo, which means browsers like Chrome and Vivaldi are good. Firefox also works. Other browsers have not been tested.

When your browser and userscript engine are ready, head to this userscript's page on OpenUserJS and install it. Please install it from OpenUserJS so that I can keep track of the downloads. You should be able to update this script directly from your userscript engine, although sometimes the engine can fail to detect updates from experience.

If you are going to use the automated gallery downloads feature, you may have to complete one or two additional simple steps to grant this script the permission it needs to download archives and/or torrents from EH. These steps are explained in the dedicated wiki page for this feature.

When you first activate this script, you should notice that there is a button that says "Configure Master Script" on all gallery lists. Clicking this button will open the GUI control panel and you can then enable the features and options you plan to use. You can read a bit more about the features in the wiki. Some recommend features and options are enabled by default, so you can see their effects immediately after this script is activated.

This control panel is built into all types of gallery lists on EH, and this should be the only thing you need to control this script. Your settings should persist between updates, so you should not need to touch the code at all. The control panel has explanations for all features and options, and notifications will tell you what to do, so in general this script should be very straightforward to use. You may want to read a bit more about the relatively complicated automated gallery downloads feature in the wiki, though.

After you have changed the settings, remember to click the save button in the top left corner and refresh the page like the notification will say. Then you can start enjoying a better EH with my script.
