Please check out this set of easy to use simple mockups. Simply open the PSD you wish to use as your mock-up, double click on the layer named "EDIT ME" and you will open up a new canvas which you will be able to save your image/graphics onto. It will not ask you where to save once you have completed, just save it. Once you have saved it go back to the main PSD mock-up you previously opened and you will see that it has been updated with your own image and graphic!
Changing Iphone Colour - Only have one of the Iphone Layers visible to have the colour adjusted.
