Get medium image height and width

[noisebug]

I need to grab the medium size of an image. I initially thought the keyword was MEDIUM_IMAGE_HEIGHT/MEDIUM_IMAGE_WIDTH but that returns the value from the admin panel.

Suggestions greatly appreciated.

Got it.

require(DIR_WS_MODULES . zen_get_module_directory(FILENAME_MAIN_PRODUCT_IMAGE)); 
	list($width, $height, $type, $attr) = getimagesize($products_image_medium);

then assign $width $height as needed.

Cheers,
NB
