Export embedded images from an Illustrator file

This is helpful if you get a web design mockup created in illustrator, and you want to quickly pull all the photos out of it, to use in your website build.

File/Save-As and choose SVG for the format.

In the SVG options window that shows up next, choose Link for the Image Location option.

This will save out all the embedded images in the same place that you choose to save the SVG file.
