Probably because you had them cached on your computer after seeing them once. I can't see either of those pics.
I think you may have to get the picture from the actually site it's on, not google. If you've done that then I have no idea.
I've never had a problem when I right-click an image and "copy image location" and put it straight into the image link box here.
Pick an image provider that doesn't hate direct linking. Whatever server those images are on is intentionally blocking direct links to images that don't come from the web page they're on.
Stand on one leg in your front yard, wave your land line telephone over your head, and cluck like a chicken... [/FunniestDickVanDykeShowEpisodeJoke}
