This feature reduces the image size (of any images in your WordPress post/page) to make it more bandwidth and screen friendly for mobile users. The problem is that it uses a PHP5-only call of file_put_contents(..), which fails without error, or logging, on my WordPress install.

To remedy the problem, I substituted the call, in 2 places, with the PHP4 equivalent calls. file_put_contents(..) is a shortcut convenience method which is the same as calling fopen(..), fwrite(..) and fclose(..).

As of version 1.1.3 of the plugin the code is under wp-content/plugins/wordpress-mobile-pack/plugins/wpmp_transcoder/ in your WordPress install directory. The 2 occurrences are in the file wpmp_transcoder.php on lines 431 and 448 respectively.

I changed

@file_put_contents($full_location, $data);

.. to ..

$fhout = @fopen($full_location, "w" );
@fwrite($fhout, $data);
@fclose( $fhout );

.. and ..


@file_put_contents("$full_location.meta", "< ?php $"."width='$width';$"."height='$height';$"."type='$type'; ?>");

.. to ..

$fhmeta = @fopen( "$full_location.meta", "w" );
@fwrite( $fhmeta, "< ?php $"."width='$width';$"."height='$height';$"."type='$type'; ?>");
@fclose( $fhmeta );

.. and all was well again.

You could also just not use the “Shrink images” feature to avoid having to mess with any code!
