Image upload and resize problems

November 28, 2007

Came across a problem in an application where 6 large photos were being uploaded and resized simultaneously. I suspected it was a memory problem, as it’s been working fine for a long time. I increased  upload_max_filesize in php.ini, which half-worked – I could now upload 2 large images, but not 6 like I needed to. Turned out I needed to increased post_max_size too (again in php.ini).

Note that if upload_max_filesize is exceeded then [‘tmp_name’] fields in $_FILES will be blank.

One other thing worth mentioning that I came across when working on the same application a while ago is I found I also had to increase memory_limit (in php.ini) way beyond its default to allow php enough memory to resize big image files.

    Try increasing the memory size in your php.ini fil to 64MB it worked for me…
