In a previous post I explained why we decided to convert most of the images on this site from PNG to JPG and how we used ImageMagick to batch it.

What I didn't get into is how we updated Drupal, our CMS,  to point to all these newly converted files. Manually uploading and updating nearly two hundred new images through a web form is time consuming and boring. Finding a non labor intensive solution can also be time consuming... but so much more interesting!

Once you know how, it's not really that difficult.
