I want to create a thumbnail image. But I don't want to physically resize each image before uploading it (actually, my client doesn't really have the capability).
Can I dictate a height (i.e. 108 px) and have a PHP script that will proportionately size down the image using that height? So, if the original is 360 px wide by 540 px high, the image will automatically size to 108 px high by 72 px wide. How would I do this?
