I accidentally deleted a few of my pictures, & it is VITAL that I retrieve them!
Does anyone know of any free or cheap (that do NOT require a subscription) websites or software programs I can download?
Btw, I don't know if it matters, but I accidentally deleted them while viewing them from my computer, not my camera. & yes, I checked my recycling bin, hoping they'd be there. No luck. :(

Try a free program called Recuva you can download it from here- http://www.piriform.com/recuva/download/… to retrieve the files from your hard drive or the SD card. If the deleted files haven't been overwritten Recuva should find them.
