1)When I put photos on my Samsung Amazon tablet to use it as a viewer, most of them work okay. But two or three of them in, say, a batch of twenty, don't display properly. They come up briefly then the screen goes blank. This happens to specific frames and not to the others. They are all JPEG images shot with the same Canon DSLR. It happens whether they are in the computer or on the SD card.
2)Am I the only one having trouble uploading to YouTube and Flickr. They reject my user name and password even after having verified them. Nor do I like the new Flickr format. They both seem to have gone overboard on security. These are sites for amateur photographers to display their work; not the CIA.

I am not sure about your tablet problems, but youtube and flickr problems smacks a little of virus or malware.
Also with flickr I discovered that you can potentially have two accounts if it isn't set up properly.
