The photos I take with the Canon Rebel XTI are all at 72dpi when I open them in PhotoShop. The graphic designer I am working with has requested 300dpi. What do I need to do so my photos will be shot and recorded at 300dpi?

You should not have any problems. ALTERNATE WAY TO TRANSFER PHOTOS TO COMPUTER If your photos are stored on the memory card, then removethe memory card from the camera and insert it into an USB memory card reader.Connect this USB memory card reader and memory card into the USB port of yourworking computer. Your computer will see this as an USB Mass Storage Device oran external storage device; you can then open the folder on the memory card andcopy the photos to your computer.Memory card reader is a handy device and is inexpensive. Youcan copy photos from other cameras and you can also download photos off yourmemory card to someone else's computer without the need of installing anyprograms.
the common difference between canon and nikon is the color they produce. you can try to change the White Balance setting on your Canon to the suitable mode e.g cloudy, tungsten, daylight, etc. if you still feel that the picture is dull, don`t be shy to use graphic software such as Adobe Photoshop, Picasa, etc. to enchance the color/brightness/contrast of your picture
I think it might be a lens issue. make sure you change the macro option. the macro must be activated if you are taking a picture of something which is close to the camera. if it's not activated, the picture will not be focused. The same will happen if the item is far and the macro is ON.
You can actually still keep taking photos with your camera without loosing the images. The XTi will never delete the images off a card unless you press the trashcan key and tell it to "delete all".
It's always good practice in these situations to have a memory card reader handy. You can pick up a compact flash reader for your XTi for about $14 at BestBuy or many other retaillers.
But to answer your question: Use the ZoomBrowser EX software that came with the camera. If your Picasa is set to automatically connect and download every time the camera is connected - temporarily disable it. That way it wont inturrupt Canon's software (which I prefer).
What you are seeing is the difference between "pixel count resolution" and "embedded resolution". So in your example 2272*1704 is the actual pixel count resolution as recorded by the camera & 72 is the embedded resolution that tells the software (in this case photoshop) what the intended use of the picture will be.
72 ppi is the default for web pictures. You can change this in photoshop by going to the "Image" tab & select image size. The window that opens will show you the pixel dimensions i.e. pixel count resolution and the document size & resolution 72.
You just change it to 300 for printing. You can change the default to 300 by going
"edit", "preferences", "units & rulers" and setting the values for "new document
