Are you using 1 of the pre-made template?  Or did you make or modify the template?

Are you using a CSV data sheet?  If so then you can just put 2 row in the data sheet for that image. Each row will have the image and text information.

If you are not using a CSV and are using the file name data option then just duplicate the image in the source folder. For the image names it would be last_first.jpg and last_first_2.jpg.  The plugin will ignore anything after the second underscore when pulling the text data for the names from the filename.

If this doesn’t helpthen I wil need to know more specific details about how you are processing to duplicate the image right now and how you are getting the text information.
