I have a bunch of pictures on my SD card. After a force reset, whenever I go into the gallery, the thumbnails are correct, but if I select a picture, it seems to very briefly show a low-res expanded thumbnail, then shows a completely different picture. It looks like Gallery is maintaining a cache somehow that no longer lines up with the SD card after the force reset. How do I clear Gallery's cache? There is no menu item that I can find for that. If I got into the Manage Applications of the settings menu I can "Clear Data" for the Gallery, but I didn't select that because I am afraid it would actually delete my pictures. When I get home tonight I can back them up and try that I guess. Anybody else seen this? Any ideas?
