Call Image from eBay Picture Service for use in Description Image Gallery Template Script

Call Image from eBay Picture Service for use in Description Image Gallery Template Script I am looking for someone who can write a script which can be used within a template as a CSS image gallery where pictures are pulled / called from eBay picture service hosting automatically. For example: a listing is created and pictures of the item are uploaded to eBay picture service hosting a standard way, once the listing is posted - those pictures are pulled within description into the picture gallery as well. So, the pictures can be viewed both ways - via regular eBay platform and in the description in the CSS gallery. I am not exactly sure if it can be done like that or an eBay app via eBay API will need to be written/developed, appreciate any information on that.
