How awesome of an easter egg would that have been?  (or is?) that some random PNG file installed with LabVIEW is actually a VI...

Just think, the millions of PNGs sitting on servers all over the world, and any one of them could potentially be a VI.

Then they all activate at once and the LabVIEW version of SKYNET arrives!

Since LabVIEW is running <sarcastic quotation marks> really stable <\sarcastic quotation marks> today, I'm not that afraid...

The paranoid side of me read that as...

I'd also like to think that any PNGs of the logo are actually VI snippets...if you drag them onto the block diagram they release the *true* power of LabVIEW.

So, you mean like this?

(wasn't sure if it would carry over if I inserted as image)

Very clever. I'm curious - how did you get the snippet without the normal snippet headers - using the Lava code capture tool, or something else?

From what I understand (not entirely sure), the code is stored in a metadata section of the PNG file. The visual part of the image is just decoration.

LabVIEW's snippet tool, edit with MS Paint, Paste new image, Save

So simple.  I can't believe I haven't tried that.  Oh, the chaos that will ensue!

Yeah I don't remember where I saw it, but I remember finding a VI (or maybe it was freeware) that would take a PNG and show you the chunks that were in it.  Chunks are just named, with byte offset and length and contain anything you want usually used for meta data.  One chunk may contain the actual image.  For a VI NI just make one whole chunk the VI file.  So if working in MSPaint does work it is probably because the PNG file just replaces the chunk associated with the image data, but leaves all the other chunks that already exist.  I suspect the CCT source would tell you more about how chunks are written.
