[Evolution] extracting embedded image

I am using Evolution 2.30.3 I received a message containing embedded pictures, and I would like to extract them as .jpg, .png, or whatever they are. The message has no attachments, and when I right-click on the images I just get the same menu you get when right-clicking on any part of a message:

[Evolution] import pine addressbook

I'd like to try switching from Pine to Evolution, but it is only practicable if Evolution will import my Pine address book. I tried File -> Import, and selected my Pine address book file, but the "next" button remained grayed-out, and there seemed to be no way to proceed. ___
