imagecreatefromjpeg and similar functions are not working in PHP

There could be a few reasons why the imagecreatefromjpeg function and similar functions are not working in your PHP script. Here are a few things you can try:

  1. Make sure that the GD library is installed and enabled in your PHP environment. The GD library is required for the imagecreatefromjpeg function and other image manipulation functions to work.

  2. Check if the file you are trying to open with imagecreatefromjpeg exists and is readable. Make sure that you are using the correct file path and that the file has the correct permissions.

  3. Check if you are encountering any errors or warnings when running your script. You can check for errors by looking at the error log or by turning on error reporting in your script.

  4. Make sure that the file you are trying to open is actually a JPEG image. imagecreatefromjpeg can only open JPEG images and will not work with other file types.

I hope these suggestions help! Let me know if you have any other questions or if there is anything else I can do to help.
