Vista - Picture Damage In Vista

Hi. I've had a heck of a time getting help from HP with issues I'm having
with digital photos on my HP a6142n.

Photos appear either partially greyed-out (the top 1/3 is visible and the
bottom half is completely grey) or there is an actual shift in data in the
picture -- the bottom 1/5 of the picture will "jump" and overlap the part
above it.

When I open a folder with pictures in it, the thumbnails appear normal.
Then, very quickly, they are "washed," one-by-one, in order, and the
thumbnails become grey or have the pixels altered.

This has happened for pictures taken on 2 Casios, a Konica, and scanned on
an HP all-in-one, so the source shouldn't be the trouble. Also, older
pictures were on a XP system before with no trouble (and new pictures, even
still on the SD card in the memory reader, are damaged, too.)

I have done a full system recovery, and even that does not change anything.
This is not an issue of doing "touch up" work by adjusting red-eye, etc. --
most of the picture simply disappears and becomes grey. I don't have access
to my XP machine now, so I don't know if the damage is permanent, but, after
viewing a picture on an SD card and then re-inserting the card into my
camera, the picture is damaged in my viewfinder as well, so I assume the
damage is permanent.

I've searched the web but haven't found any similar experiences. Has
anybody had this happen? And did you find a solution?

This problem occurs when Vista cannot fully read an image file.

You need to check two things. First, your computers card reader my be faulty, and second, the SD card itself may be giving up.
