How do i add the ability to use different photos for a test case??

I am wondering if anyone knows how to add the ability to use a directory that has numberous photos to run a soapui test. I want to use a datasource loop or something similar to allow me to use all of the photos that i have stored in a directory . I need to add information into a database and i want to cycle through a grouping of photos so that i can enter new name/address with each photo. Can this be done in Soapui? the photo field shows up as a xsd:base64Binary
