How Do I......??????

I have been spending a ridiculous amount of time puttering around on The Graphics Fairy's blog lately, and it has been so much fun! I have made several projects for our soon-to-be home, and hopefully I can get some pics up soon.
Here's my dilemma.....many of TGF's images are centered left, rather than middle. How do I scoot them over so that I can fit more than one image on a printed page, or so that I can also add lettering? Obviously I am computer-challenged, so if anyone out there could help me out, I'd greatly (GREATLY) appreciate it!!!
