Well yes and no.

I went back and checked - if you click on the thumbnail it takes you to
a bitmap file. The first sky scene is a 28.7meg file.

But if you right-click on the thumbnail and save the target image, it's
a jpg...very weird behaviour.

I have both here and I've compared them - they're the same image, just
two different formats.

Including the same resolution? (Obviously not the same size,
given how poor BMP is at compressing -- that is, it doesn't. :-)

I'm not even sure that my system could *display* a BMP image
with my browser, since BMP is native to Windows, not to unix. I do
have programs which can render the images, but as I said, I'm not sure
about the browser (Opera, FWIW.)

The first image I just downloaded directly using "wget" (no
browser involved). The second one (the one with a tower in a gridwork
as the central part) I clicked on the thumbnail, then selected to save
the resulting image to my system to check -- and both of those were
JPEGs, and both with full exif data. I don't *think* that my browser
would download a BMP and convert it to JPEG -- and miraculously preserve
the exif data, which I don't think can even be included in a BMP image.
:-)

Enjoy,
DoN.
