I use the image thumbnail library (Laravel resizer package ), which takes jpg from the directory and uses imagesx() to save this image in a different size. This works without errors most of the time.
Problem: However, sometimes when there is a batch of images for processing, I get an error below. During debugging I did
.... print_r($this->image); imagesx($this->image); ....
PHP output

Together with the stack trace above, you can see that $this->image is false right after its Resource id #166 .
Any idea what could have caused this? I do not understand why sometimes this can be false . Thanks!
