Open the 1688 website in a web browser, find the pictures you want to download, put the mouse cursor on the picture and right-click to select "Copy Picture Address".

Then open the batch download software, such as IDM (Internet Download Manager) or Free Download Manager, paste the copied picture address, set the save path and file name, and click Download to batch download. Note that you must comply with relevant copyright laws and regulations and the regulations of the 1688 website when downloading, and you may not use unauthorized pictures for commercial purposes.

If you need to batch download pictures from 1688, you can try the following methods:

1. Use browser plug-ins

There are some browser plug-ins that can help you batch download pictures from web pages. Among them, the more commonly used plug-ins include "Batch Picture Downloader" and "Picture Batch Downloader". You can search for these plug-ins in the browser's app store, and after installing them, you can batch download pictures from the 1688 page.

2. Use third-party tools

In addition to browser plug-ins, there are also some third-party tools that can help you batch download pictures. Among them, the more commonly used tools include "Thunder" and "Internet Download Manager". You can first copy all the image links on the 1688 page, and then use these tools to batch download.

3. Use Python scripts

If you are familiar with programming, you can also use Python scripts for batch downloads. You can use the "urllib" library or "requests" library in Python to write a script to get the links of all the images on the 1688 page and batch download them.

Whether you use whichever method, you need to pay attention to some legal issues. If these images are protected by copyright, you need to obtain authorization from the copyright owner before you can download and use them.
