Have you tried using the Wand tool to remove the white background? Might look into using Opacity tool. You'll need to merge all the layers and then save in the format you want to use. Would you want to keep the shadow behind image?
Fantastic, thanks. I'm going to have a go at that as soon as I have a few minutes. I may want to put just a very subtle shadow, I think subtle effects like that can draw the eye without taking over she show.
