Spacing between images

Hi….having issues with my images lining up correctly. These images do not have any white space at the top of them. They were sliced from Photoshop perfectly and I did NOT do a “Hard Return” when placing the bottom two images. Any way of fixing the gap between the pencils? This is one of the reason I have always hated HTML….but I thought WordPress would be easier. I’m frustrated so please help if you can!
Thanks,
Russ
