I am very much interested to wok on this project. I have good expertise on eBay store design and listing template design.
I check your image, HTML and requirement.
For This we make one script.
In this script we do following things for use eBay listing image:
1) Import your all products in our database
2) Get all image title, description and image path
3) Use that all details and revise all items.
So you get all image which you use in eBay product part. But if you update product image then it automatic not update in HTML part.
But with this script you not need hosting for eBay product image.
So if you like this method we can work for you.
Looking forward to your reply.
Thank you,
Yasin
