In using windows 7, how can i view and download pictures from my canon powershot a560?

If those pictures were not taken on another A560 then yours won't be able to display them.

Yes,there should be a special cable for every canon powershot cameras to connect with PC. Good luck!

You can download Canon software from

You might want to consider NOT connecting the camera to the computer.

The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive. Or you can use any photo cataloging program.

Windows updates changes the registry and sometimes causes our "toys" to stop working. You can contact Microsoft and get instructions to re-write your registry(very dangerous if you don't know what you're doing) or, you can do what the pros do to avoid this very common problem....get a card reader!

How is the battery condition?
Maybe they need charging.

Use a card reader instead of your camera.

Use a card reader to download your pictures to a folder you create on your desktop.

The date and time (and a lot more) are stored with every picture in its EXIF metadata. Any photo viewing/editing program should be able to display this data. To print this data, please consult the documentation for whatever program you're using to print your pictures. Depending on the program and printer you may print the date on the image, in the margins, or on the back.

Go to Canon Support and Select OS (Windows etc) and download required zoom browser software. Install it and have fun with A560.

Take the camera about 6 inches away from the card. Use P mode on all automatic settings, but use the MF flash (press the close-up tulip twice, on the bottom of the navigation wheel), set to 15 cm (use left and right buttons to adjust). Try putting the camera on a mini tripod and the card in a holder to minimize camera shake. Also, ensure that the optical image stabilizer is on. When viewing the taken picture on the camera, zoom in as you would when taking the picture to see the picture at full resolution.
