The problem is probably melted insulation material on the shutter blades........this happens constantly with these Canons and I have cleaned over 100 of them.

I have the same problem and sent a email to Canon and this is their response.

Thank you for your inquiry. We value you as a Canon customer and appreciate the opportunity to assist you. We are sorry to hear that theflash exposures with your EOS Digital Rebel XT and EF 28-135mm lens are exhibiting a shadow along side the image.

What you have described could have two possible causes:

1. The lens barrel is partially obstructing the flash. (The shadow
will generally have a curvature to it.) Try a different lens or focal

2. The cameras shutter is not fully synchronized with the flash,
therefore, causing a portion of your image to be underexposed. (The
shadow should be even across your image.)

If this issue only occurs with this particular lens, then your lens will need to be examined. However, if this issue persists with multiple lenses, your camera should be examined. We regret this inconvenience.

Please forward your digital camera and/or lens to the Factory Service Center shown below. When shipping your camera, please be sure to removethe CompactFlash card and battery.

Do you have any samples you can post? Does it happen with the self timer on a tripod? This is probably caused by your hand being in the way of the flash. Post some samples and we can get a better idea of whats happening. =)

SOURCE: dark shadow on right side of picture

sounds like a shutter leaf dropping into the image. however, they are usually horizontal and more likely to manifest when in landscape mode. (horizontal, normal)
try using flash pointed up to ceiling.
also, could need to check for auto sync speed setting. usually 1/125 to 1/60. if its off, it could be catching the shutter in the wrong place.
check manual for settings for using flash.

Canon 1400 IS: When I take a picture using flash of a close up object, a shadow is cast on the lower right corner of the picture. For pictures that are not taken close up with flash, or taken from further...

It's most likely the shadow of the lens. The flash is above and to the left of the lens, so the shadow of the lens will be to the right and below.

Uneven flash

Look carefully at your images taken with flash... on the horizontal image is the lower part of the image slighty darker and have a rounded fall off at the edges? Is the vertical image dark side a straight hard line or is there a rounding to the top and bottom?

What we are looking at is if you have a very wide angle lens with the lens shade attached to the lens, then the built-in flash catches part of the lens shade and make a shadow on your subject... take the lens shade off and try the same shot and see if that makes a difference...

Have a great day...

Shadow across photo

Shadows, especially circular shadows, are pretty common with the pop-up flash. What you are seeing is actually the shadow cast by the end of the lens. This happens especially on wider angle shots.

The solution is to find a way to get the lens out of the way of the flash. You can get an external flash, like a 430ex or 580ex, which elevates the flash far above the lens. That is an expensive option so first you might try making a diffuser for your pop up flash, which softens the source of light and helps eliminate some shadows:

Why do some of my pictures come out dark or with shadows?

Your Polaroid Fun! Digital 320 camera does not have a flash. If pictures are coming out dark, it's because there wasn't enough light in the surroundings when the picture was taken. Remember, it's important to take photos in brightly lit surroundings. When taking pictures indoors, make sure that the room has bright lighting. For best results, take pictures during daylight hours with a combination of indoor and outdoor light, preferably near a window.
