or reverse google image search

This tool would have saved me some time.
But I used google, and after a few minutes I found her.

How do you do reverse google search?

Thanks so much for sharing, Rod, I've bookmarked that site!

you go to google image search

inside the search bar is a little icon of a camera
click that and a menu pops up where you can either upload an image or insert an URL

also there is some add-on that lets you right-click an image and search for it via google

You are very welcome.

Thanks Esper, I figured it out!

Here is what I have so far, with the text. I don't like the text at all, I made a new thread to ask for suggestions on that....

Doesn't look very realistic to me for several reasons:

1. The inside picture is "soft" while the outside is very sharp and contrasted (looks even like a HDR). If that were a window, this would be the opposite, because the window reduces the contrast.
2. The reflection itself is too sharp
3. If the glass/Mirror is about 25-30° from the viewer, the reflection should be rotated 50-60° so we should see the girl almost from the front. This has been discussed in another thread, it is about impossible to make a realistic reflection by simple transforms except in some very trivial cases, since reflections show things that aren't visible in the direct image.
4. And even assuming the direction is good, I don't find the reflection to be physically sound. The elbow isn't reflected when the dark suit is and IMHO it should be the opposite. The reflection is slightly darker than the source, but between the reflection and objects on the other side of the mirror, what you see is the more luminous one, so the black suit should be invisible and her arm blended in the building (technically: duplicate layer, flip, darken, blur (remark #2), add layer mask initialized from B&W copy of layer)
5. The mid-point between the two noses is above the railing, so that means the railing is embedded in the glass. Normally you should have a reflection of the railing, and that would alleviate the problem with her hand (strange upper railing, by the way, it is interrupted just before the girl's arm, then reappears under her armpit, then disappears again (but the second dancer uses the lower one anyway))
