Canon Powershot A570 digital camera I had around 250 images in my memory stick, but all of a sudden when I tried to click another photo, all the images disappeared and showed the last picture clicked 1/1 on the bottom left corner on the display, but the top right hand corner had 1/250 but I couldn't see the images on the screen. I tried going into the menu to see if I could access thoses photos, but it showed change battery and had taken me to the Format screen without me have clicked any settings In the format screen there was a tick in the low level format and the camera switched off automatically. When I tried to switch it back on it said no images. Is there anything I can do to get thoses images back.

As all your photos are stored in your Canon digital camera's memory stick you could tryCard Data Recoverywhich will help you recover pics without casusing any damage to your photos. My bff recommended this extremely easy-to-usel software to me and he had used it successfully to recovered photos, music, etc. from his Sony memory card. Best wishes!

Take no more pics until you've recovered the photos, take the card out of the camera. Here's some freeware photo recovery software that should be what you're looking for:

You will need to use a flash card reader with this software. If you don't have one, get one, they're cheap:

After you've recovered your photos, go back in the menus to that "format" screen. Make sure that "Low Level Format" is checked. Then format your card. This should help prevent this from happening again. This will also erase any photos you may have on the card, so again only do this after you've recovered your pictures.
