When I edit the reunion section, my pictures are vertical and everything looks great but when I go to the website and look at the reunion section, the images are lining up horizontal and the page is extremely wide. What do I need to do? I still need to add more images to this page.

I looked at your site and it looks like you've already figured out how to fix this.

After each image you should pres the Enter key a time or two. Pressing enter will cause your next image to drop down to the next line. If you upload two images in a row and do nothing to tell the second image to go onto the next line, the images will align horizontally, which can have the unanticipated effect of blowing out your content area.
