Need Help In Corel Photo Paint

I had a company send me a saying that has a black back ground and white print. I am trying to get rid of the black back ground and then copy the white print to resize and put on a t-shirt. Can this be done? Can anyone tell me how if it can be done. 

I am new to Corel products so this is a challenge. Should I be trying to do it in Corel Draw or Corel Photo Paint?

I only of a trail subscription and it will be over in a few days. If the program will not do what I need done I do not what to buy it. 

Any help

Thanks

Thanks for all your help. I tried it with the transparency tool and everything turn white so I could not see the print. Here is what I am working on. I am just trying to get the writing on pictures of different color shirts.
