How to import multiple images with Feeds importer from CSV?
You can accomplish this with choosing a character to separate your image urls with in the CSV file and using the Feeds Tamper plugin "Explode".


Separate the image URLs in your CSV file with a certain character, for example a pipe character: "|". Your CSV file could then look something like this:

title,image
Lorem Ipsum,http://www.example.com/image1.png|http://www.example.com/image2.png
Install the module Feeds Tamper. Also enable the Feeds Tamper Admin UI module (included with Feeds Tamper).
Go the Tamper page of your feeds importer (/admin/structure/feeds/[importer_id]/tamper).
Click "Add plugin" for the "Image: URI" mapper.
For the plugin to add, select "Explode". As string separator, choose the character that you used to separate your image URLs. If you followed the example, then this would be the pipe character: "|". See also the image:



The explode tamper plugin cares that your input data (for example "http://www.example.com/image1.png|http://www.example.com/image2.png") is handled as multiple values.
