If Temu cannot crop images, there may be the following reasons:

1. Image format not supported: Temu may not support the image format you are using. Please try to convert the image to a format supported by Temu, such as JPEG, PNG, etc.

2. Image size limit: Temu may have a limit on the size of uploaded images. Please check whether your image size meets Temu's requirements and try to reduce the image size.

3. Browser compatibility issue: The browser you are using may not be compatible with Temu. Please try to change to another browser or use a browser recommended by Temu.

4. Network problem: Sometimes an unstable network may also cause image cropping failure. Please check your network connection and try to operate in an environment with better network conditions.

5. Temu website problem: There may be a malfunction on the Temu website. Please try to operate again later or contact Temu's customer service staff for help.

If the above methods cannot solve the problem, it is recommended that you contact Temu's customer service staff to ask for specific solutions.
