For a number of my astroimages—the supernova in M51, for example—I have wanted to point to things with a marker. But I wanted it to pop up as needed. Of course, that's easy to do in web pages with JavaScript and mouse rollover event handling. I just didn't know if it was doable inside blogger articles...
Tried it on the image of Pallas I shot back on 2 Aug. Works great!
And it turned out to be even easier than I thought!
