Creating randomised photo survey in R

I am new to stackoverflow so please bare with me! I have a dataset which includes a reference code for the people in my data, and details about them. I need to create a photograph survey which will give me an image of a child, his/her father, and 2 other men in the same age category. I have already sorted my data in R and have the names of all the children, their fathers and men in that age category, but I don't know how to attach photographs to R...is this possible? If so how can I randomise the 2 men from the same age category?

Many thanks
