Not a doc problem, so changing category to "GD related".

this is a doc problem. It must state that some versions of PHP (e.g. prior to 4.3.9 or else) has a bug that doesn't allow to enter empty string.

Which version are YOU using?

An empty string is an invalid path. If you want to output the image directly and still change the default compression mode (3rd argument), pass NULL:

imagejpeg($im, NULL, 60);

It could be added in the image* doc, but it is the way it works for any other php function with many optional arguments back to doc problem.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
