Oh man, why did I laugh so hard?

Caramel Crunch? I don't get it.

"Caramel Crunch" is the name of the artist's website.

How can this image be a JPEG with a size of 3.4 MB!? I've checked, it's really a JPEG but how is that possible!? I can't tag it as png_overkill! Motherfuck!!! Someone explain this to me, is it the colorful background?

It's been saved as a max quality jpeg for minimal artifacts, but a magazine scan of comparable resolution yields an image about 1/3 the size at the same jpeg quality level. Seems that random noise backgrounds don't compress well.

Which is strange because there doesn't seem to be a lot of variation in color, I even re-saved it without compression but only got it down to 2.65 MB. Geez.

Maybe there's a hidden archive inside the image.

Progressive display cans that theory. The picture stops downloading as soon as it finishes displaying. Nah, it's just a really horribly compressed JPEG. And yeah, these "random noise backgrounds" are actually a huge mess of tiny areas of slightly varying color, which is hell on the JPEG algorithm.
