Build a Tkinter GUI Image Scraper and Package It as an EXE

Task Objectives

1. Scrape different types of images. 2. Write a GUI‑based crawler with Tkinter and package it as an executable. 3. Discuss encountered difficulties.

1. Analyzing Image Types

The target site displays six menu items, each representing a distinct image category. By inspecting the URLs you can see that each category corresponds to a cid parameter (e.g., "大胸妹": cid=2, "小翘臀": cid=6). To download a specific category you only need to construct the URL with the appropriate cid value.

2. GUI Development with Tkinter

Using Tkinter, the program creates a window that lets users:

Select a local folder for saving images via tkinter.filedialog.askdirectory() .

Choose an image category from a drop‑down list, which maps to a cid value.

Specify the number of pages to crawl (e.g., first 5 or 10 pages).

The layout includes a text box displaying the chosen path, a button to open the folder‑selection dialog, and controls for category and page number.

Choosing the Storage Path

The selected directory is stored in a text widget (self.input) and later used when saving each downloaded image.

Selecting the Category

A combo box (or similar widget) holds the six categories; when the user selects one, the program returns the corresponding cid value.

Setting Crawl Depth

The user can enter the number of pages to fetch; this value is appended to the request URL.

3. Problems Encountered

Some images lacked proper filenames, resulting in names like ".jpg" which caused illegal‑character errors during saving. The issue was resolved by appending a unique letter to each filename, ensuring every file has a valid name.

Overall Result

The final application successfully downloads images from the selected category into the chosen folder, respects the specified page depth, and can be compiled into a standalone .exe file.
