How do I transfer photos from MacBook to my iMac?

Here's how http://docs.info.apple.com/article.html?artnum=58583 OR even easier, if you have a USB Card Reader, you can transfer them that way. Also, if it's you don't know what the ports look like, this page shows you what the symbol for Firewire looks like. Locate it on both Macs. http://www.apple.com/imac/technology/connections.html

HI Dan... Welcome to MacWorld and Apple Discussions 🙂

To transfer files using FireWire:
Shut down the first computer and leave the second computer on.
Connect the two computers using a 6-pin to 6-pin FireWire cable. (If both computers have higher-speed FireWire 800 ports in addition to the standard FireWire 400 ports, you can use a 9-pin to 9-pin cable with the FireWire 800 ports to transfer data at higher speeds.)
Open System Preferences, click the Startup Disk, and click Target Disk Mode. (Or, start up the first computer while holding down the T key.) * Dan, it's easier to just strt up the first Mac and hold down the T key *
A disk icon for the first computer appears on the desktop on the second computer. Drag files to and from the disk to transfer them.

When you finish, eject the first computer's disk by dragging its icon to the Trash. (While you drag, the Trash icon changes to an Eject icon.)
Push the power button on the first computer to shut it down and disconnect the FireWire cable.
