无法显示图像“path”，因为它包含错误

Question

The following error is generated by drupal site creating an image using imagecreatefromjpeg and imagejpeg:

The image “http://domain.com/dbtransfer” cannot be displayed because it contains errors.

I enabled error display and checked the error log but no errors are display. There aren't any messages displaying. All the paths are correct as well as all variables are correct.

Creating and writing data into mpdf image but it's not working here.
