Multiple Image galleries category wise.

I am developing a site of a vendor.
He had 10 categories of furniture (categories may be added).
On main page, he wants an image slider containing 1 image of each category. (I have done that).
Upon clicking any image it should open the concerned category, with posts of that category. (I have done that, too)
All the stuff should be dynamically updated, as per adding in the posts.
PROBLEM IS: I need to display image slider on every category, showing the images of that particular category.

e.g
Category 1 = A, B, C
category 2 = D, E, F
Category 3 = G, H, I
etc

When category 1 opens, the image slider should show images of A, B, C ….. etc.

Someone please please please help.

Thanks.
