Cannot Upload More Than Some Specific Number of Images at Once¶

If you cannot upload more than a certain number of images at once for product options or option combinations, this is likely due to a PHP setting that limits the number of files that can be uploaded simultaneously. That setting is called max_file_uploads.

The default value of max_file_uploads is 20. It means that the administrator of the store can upload no more than 20 images at the same time for product options, and no more than 10 images simultaneously for option combinations (one additional thumbnail and one larger image).

To resolve this limitation, increase the value of the max_file_uploads setting on your server.
