Help Photo/Video Capturing and Viewing Issues

[DV Producer]

I just updated my Sensation 4g to ICS and installed a new Class 10 - 32gb Micro SD card.
When I use the stock cam app to take a picture, I am able to immediately review the new pic.
When I use the stock gallery app to view the pic, the gallery shows a triangle with an exclamation point instead of the pic's thumbnail.
When I use the stock camcorder app to record video, I am able to immediately review the new video.
When I use the stock gallery app to view the video, it says it is unable to play the video.
I just finished capturing 125 pics in NYCs Chinatown. I reviewed each pic from the cam app after each was taken. Now, I am using the stock gallery app to view all my new pics. Each pic is a triangle with an exclamation point. 0 out of the 125 are viewable. Details shows the 8 megapixel pics now have a resolution of -1x-1.
Any ideas of what I need to do before smashing up the HTC Sensation 4g against the concrete?

Install QuickPic.
This app rescans the SD card for media.

And QuickPic is a far better picture viewer than the stock gallery

Note: After QuickPic had shown your the pics and videos on your SD card, the stock gallery will do it too.
Because QuickPic had done this rescan for media on the SD card

Thanks for your Response, Harry!
I installed QuickPics and it saw none of the newly taken pics. QuickPics also sees the videos, but it cannot play them. I will install VLC later to try.
I'm lost here. I'm wondering what can make a freshly captured .jpg at full 2448 x 3264 resolution suddenly turn into a triangle with an exclamation point and a -1 x -1 resolution?
I think now I am going to remove the Class 10 32gb MicroSD Card and replace it with the 8gb card that came with the phone and take a whole lot of pics and see what happens.....
I sure hate this phone phrustration!
