Large Image on Ad Pages
I would like to allow users to display large images on their ad pages. I'd like to display up to 700 x 700 when a user clicks the preview of the image on the single ad page.
Any advice about how to do this?
I see section of functions.php has code to create images:
// create special sizes for the ads
add_image_size('ad-thumb', 75, 75, true);
add_image_size('ad-small', 100, 100, true);
add_image_size('ad-medium', 250, 250, true);
//add_image_size('ad-large', 500, 500);
Not sure why ad-large is commented out. I don't see any other references to ad-large. Is there a way for me to simply change one of these sizes?
