lets have a picture of the data:
+---------------------------------+
| data (tt_content)               |
|  +----+ +----+ +----+           |
|  |img1| |img2| |img3|           |
|  +----+ +----+ +----+           |
+---------------------------------+

in the same way you should template the data

tt_content.text_bgpic = FLUIDTEMPLATE
tt_content.text_bgpic {
     file = 
EXT:my_extension/Resources/Private/Templates/Content/TextBgPic.html
     variables {
         imagePath = FILES
         imagePath {
             references {
                 table = tt_content
                 fieldName = image
             }
             renderObj = FLUIDTEMPLATE
             renderObj {
                 file = 
EXT:my_extension/Resources/Private/Templates/Image.html
             }
         }
     }
}

and in EXT:my_extension/Resources/Private/Templates/Image.html you have 
access to all data of one image: (uid (sys_file), publicUrl, width, 
height, description, title, ...
explore by using: <f:debug title="one image">{_all}</f:debug>
