1) First of all, make sure you download the JPG and PSD versions of the Prompts. onto your computer at home.
2) Install the fonts onto your computer.
3) Open up the background.psd in Photoshop on your home computer. Customize the text, colors, etc. and then save it as background.jpg. Put this new file into the prompts folder on your desktop. Make sure you backup and then erase the old one. DSLR Remote Pro should now recognize the new background.jpg and start printing with that graphic.
