Open that image in MS Paint. Now add text(your poem) and save it to jpg again.

Open the image in MS Paint

For adding text, click on the symbol 'A' on left hand side. When you click 'A' it gives you two options to add text. There will be two coloured boxes on left hand side. One will allow you to add text without erasing the picture and one will allow you to add text by erasing the picture under text box. You just need to copy your poem and paste that in the text box in MS paint.

Hope I am clear.
