Well, if the .png file contained alot of detail or was a photograph, for example, I might use the browser function "Open image in a new tab" to look at it in more detail. But if I do that with png images served by appengine, the resulting behavior -- an image download in Windows, or a quicktime logo in OS X -- makes my app look more like a high school project with a bug in it than a professional site. Rather than live with this strange behavior, I'll apply a workaround.
Side note: I see that this issue was first reported to the Chrome team 3+ years ago (issue 25293<https://code.google.com/p/chromium/issues/detail?id=25293>), so it's obviously not a priority at Google.
