or, what are those 3 images at the bottom that I've never seen before?

seriously.. I have 3 images on there I've never seen or clicked on. never seen 'em before in my life... so where did they come from? I've attached a view of 'my recent views' to show you. the ones ringed in red are the images in question ('timelights globe' was moved to the top row after I clicked on it to see if I recognise it.. I don't)
