First you have to get the template. The site I use to make my shirts is blingee.com, so what u'd have to do is right click on the girl template and press
Save Picture As.. and obviously save. Than u'd go to blingee.com and make an account if u dont and than press
Make a Blingee!, than browse and than click the template and do what ever u want w/ the stamps below the pic. If want s certain stamp that's not there than u'd go search which is at the bottom of the category list and type in a keyword u'd like for a stamp. And when u want one press add and it will be added to ur Goodie Bag. When ur done and saved on the side w/ the options press Get Code/Downlad, choose ur size. Than u go 2 the bottom of the page click and copy the long code than just go back to the t-shirt contest, postreply and paste it there and it should show ur pic
For example her's mine for this week[dont copy!]:
