I'm going in circles on this. In the past, picasa would allow me to view thumbs of my raw files and give me a "slideshow" if I double clicked on a picture. But with the new 5d3, picasa has not updated the program to work with these new files.
I've downloaded Canon's codec pack.
I've downloaded Microsoft's codec pack.
I've downloaded windows live gallery, which gives me a slideshow preview, but no thumbnail preview.
I would really like to be able to view the thumbs in windows explorer. I have Win 7 64 bit. Anyone know what else to do?
