Listing with multiple items

[dorismw2]

Hello, I am fairly new with ebay and I have an online store. I would like to put items from my store on ebay. May items are similar and i would like to use the multiple item listing. I have added all my photos and am down to the next which is Variation Combinations. I understand all of this. My problem is with the photos, each line includes the main photo only. I cannot figure out how to change the photos for each item to correspond. I would like to see a basic primer for ebay listings to help us newbies.

Thanks for any help you can give.
