The Temu front-end image search not working may be due to the following reasons:

First, it may be a browser setting problem. You need to confirm that the browser supports JavaScript and has enabled cookies and cache, etc.

Second, it may be a network problem. You need to check whether the network connection is stable and whether the firewall is set to prohibit requests, etc.

It may also be a source code problem. You need to check whether the source code has vulnerabilities or errors, and whether it matches the back-end interface.

Finally, it may be a data set problem. You need to check whether the data set is reasonable and whether it contains the required data. Solving these problems can make the Temu front-end image search work normally.
