+# eh_download
+dgeh, Download Gallery E-hentai.
+
+GUI gallery downloader for e-hentai and possibly nhentai
+
+Once you downloaded all the files you want, I suggest using this script : https://gist.github.com/toiletclogger69/d08164cd8c978f7a1fc2f12ee9e4f15a to easily read the gallery afterward.
+
+## **DOWNLOAD THE EXE HERE [dgeh.zip](https://github.com/toiletclogger69/eh_download/files/8010577/dgeh.zip)**
+
+## requirements (as an exe)
+None, just click on the exe
+
+## requirements (as a python script)
+```
+pip install gooey
+pip install requests
+```
+
+---
+
+## Screenshots :
+The GUI : 
+
+![Screen1](doc/url1.png)
+
+The result of downloading 4 gallery :
+
+![Screen2](doc/url2.png)
+
+In each folder every picture :
+
+![Screen3](doc/url3.png)
+
+---
+
+## Fields
+**Text area** : Put a list of url inside the box, eg:
+```
+https://e-hentai.org/g/lots_of_number1/lots_of_number1/
+https://e-hentai.org/g/lots_of_number2/lots_of_number2/
+https://e-hentai.org/g/lots_of_number3/lots_of_number3/
+```
+
+It only accept url from e-hentai (eg : https://e-hentai.org/g/lots_of_number/lots_of_number/) and nhentai (eg : https://nhentai.net/g/lots_of_number/)
+
+**Replace character** : Remove every | ? ! and other character that are not accepted in window folder name.
+
+## Use a standalone script
+Go into [eh.py](eh.py), set `TRUE_IF_CLI` to True.
+
+Add a text file named "urls.txt" in your current folder, put every urls inside then execute the script with "python eh.py".
+
+## Issue with nhentai
+I can't access easily that website so I can't test if the script works. 
+
+In theory it should, if you get an error saying forbidden access (Cloudflare protection against bot) I can't do anything about it.
+
+## How to build the exe
+`pip install pyinstaller`
+
+go into the current folder >
+
+`pyinstaller build.spec`
