Newer versions of wordpress autofill the alt text using the image's file name, any way to change this code to get around that problem?

Using get_the_title() to populate image alt tags is a bad idea. If you have multiple images they will all have alt tags that say "6579540 Ways To Be A Rock Star" even if the image is a toilet plunger stuck to someone's head. It's just not good.
