Importing content to a content type with images and associated data

Question

I'm trying to import images with ALT text and tooltip text into Drupal for a content type.

I'm using Feeds and Feeds Tamper to import the rest of my content right now, like so: http://learningwithsage.com/wp/?p=212

And here's a technique for importing just the images: https://www.drupal.org/node/1851322

But I'm still unsure how to do the tooltips and ALT Fields for the images.

Anyone?
