I am creating a very simple cover for my book project using the front cover template from Lulu.com. Lulu's instructions are to: "lock" the template, and add a new layer within the bleed cut-off zones. I am having trouble doing so. First, I cannot lock the template layer. Secondly, when I add my image as a new layer, the template layer shrinks. When I try to resize the new image to 'match' the two layers, nothing happens. I need to be able to fit the new layer inside the template borders.
How do I
*lock the template layer?
*resize my new image layer to fit within the template borders?
