Sandisk makes a free recovery program that I've found works extremely well - it can even recover photos off of formatted cards, as long as they haven't been written over.
Search for Rescuepro...I found one free downloadable link here:

(I do not know the company or site, or have any affiliation).
It often comes free with any high end Sandisk card purchases - I got one with my CF card years ago as a tiny disk, and loaded it on my computer. Never used it for years, until one time I forgot I had a card with photos that were never downloaded, and formatted the card - realizing almost seconds later that i never loaded the photos. RescuePro retrieved them all with no problem.
If the card is completely fried and won't be recognized at all by any programs, you may be out of luck. If you cannot get the card to recognize no matter what you do, and you've already decided the photos are gone forever, maybe try formatting the card so that it can be read again, then use Rescuepro to see if they can be retrieved. But I'd try rescuepro BEFORE formatting too, to see if you can pull out the photos.
