Display multiple images side-by-side

I am using CR XI. I am building a report to display parking ticket information and up to 4 photos side-by-side beneath each detail record. My photos are stored on a file server, not in the database. The filenames are identical except for a sequence number appended to the end of the filename. I am able to display the first jpg image using a formula to construct the file's path: Insert Picture> Format Graphic> Picture> Graphic formula editor. Placing additional photos forces the report to expand the detail section to accommodate the 2nd, 3rd, etc photo. The first detail record shows a placeholder image where I want to see the second image. I can conditionally suppress the placeholder image - that's not the problem. How can I make the photos display side-by-side?
