It is no problem whatsoever to download a front or back cover template from a self publisher like Lulu and create a wonderful cover using Paint.Net. All you have to do is layer on images and type in text until you arrive at the effect you want in either a front or back cover.
With Lightning Source cover templates things are much more difficult. Their templates arrive in either INDD or PDF format. You must have Paint Shop Pro to work with the first file type. Alternatively, you can use the website ZAMZAR to convert a Lightning Source PDF template to PNG format.
So now you have a three piece template, front cover, back cover, and spine, you can load into Paint.Net. That's the good part! But the hard part is, how do you add images seperately to all three elements of the template resting on your workspace in Paint.Net?
I would like to take the seperate front and back covers I designed in Paint.Net with Lulu templates and import them into the Lightning Source three piece template. How do I do that?
