Borders

[Cyph]

Hi all, new to the boards and first post

I have a project in mind where I use screen shots from games and make comics out of those (not a new idea I admit). I have made one page, and I like the end result, but it took me a long time to make the white borders (I don't know what these are called in english, sorry) that seperates the pictures on the page, and I can see that I will run into a few problems such as making sure the width of the borders are the same on each page, etc. I wondered if there is any downloadable template somewhere so I 'just' needed to fill in the backgrounds and come up with the text?

I use Photoshop but also have Illustrator.

I apologize if this has been answered in another thread - I did look around but could not find what I am looking for.
