I am trying now to prettify my PHP script references in this post: http://wordpress.org/support/topic/68468
Basically, I want to be able to do a popup of an image, but in order to size the popup window appropriately, I need to check the image size before I do the popup.
I don't see any built-in WordPress functions that would do, so I'm trying to use the PHP function getimagesize().
I first passed the absolute pathname on the server:
And got an error. Then I tried a relative pathname from the theme's directory (since that is where my PHP template file is and it seems to be referring to that as the base):
Then I tried dumping the pics inside a subdirectory of the theme directory:
In all cases I'm getting an error similar to this:
Warning: getimagesize(/images/gross/DSCN6749.JPG): failed to open stream: No such file or directory in /home/content/j/o/h/johnsgd/html/wp-content/themes/almost-spring-hacked/gross.php on line 70
Is there some secret sauce for accessing files directly via the PHP functions?
