First do not panic! It is possible to recover your pictures if you take care. Take the card from the camera (powered off) and if it has a "write protect" tab then lock it now. Do not try and write anything to the card or you risk causing more problems.
You can either plug in you camera to the PC as it should appear as a “Removable Drive” or put the card in a card reader attached to your PC.
Next, if you are comfortable with using a PC then you can download a FREE utility that will recover your photos from the following link:http://www.cgsecurity.org/wiki/PhotoRec
If you need something a little more "user friendly" then you will need to buy the software. If you search the web for photo recovery software you will find many.
One I have used successfully is RescuePro that used to be bundled with some Sandisk products. Now you can get it from the link below:http://www.lc-tech.com/software/prwindetail.html
You can try the demo to see what you can recover before buying.
Remember - Do NOT try & write anything back to the card until you can recover your pictures to your PC safely!
