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.

Just delete some pictures you have taken. You can use memory card reader to copy your pictures to computer and then delete some picturse or all of them. And you can delete pictures directly with your camera. On the back side you can find delete button it hase simbol of basket.

Hi. I have used an older model ELPH camera its quite nice. It sounds that you are using the cable from the camera to the computer to download the photos. I do not know why the error occurred (probably a weak battery ) . Have you tried taking the memory card out of the camera (push it once and it pops out), then insert it into a special SD adapter connected to the computer by USB? Image google sd adapter usb if you do not know what that is. Some computers have the SD slot built in the side. After that on a PC click Start/My Computer where the card should appear as an external storage device. Click on that and on any folders within and your photos should all be there. Select all (Ctrl+A) and copy/paste them into a folder of your choice.

Use a USB card reader on your computer.

Have you ever "formatted" (not erased) the card in the camera (noting that this will also erase any pictures that you have on the card)? There are several possible causes for memory card errors. Troubleshooting tips for this problem may be found at this link.

My cards have messed up before and I have always been able to fix the cards and retrieve my pics and all files with these programs....

You probably just need to format the card in the camera. This will completely erase it so download any pictures you want to save first.

The process only works one way...you can download pictures taken on your camera to your computer but you cannot download pictures from your computer to the card and play them back on your camera.

This Canon uses an SD memory card (previous Canon used CF cards).
The SD memory card has a "slide switch" that locks the card.
Look at the SD memory card and move the switch back and forth, then switch it all the way to the UNLOCK position. Put back in the camera and format the card, then use it.

Since this is a 10Megapixel camera, use at least a 2GB SD memory card. A 2GB SD card will hold 700 pictures, or so, in the best setting.

Hope this helps!

These cameras are on the list of the ccd problems.
