  (@Step 14) Almost correct. I suppose it depends on what browser you are using, but on Firefox you can still right click on it. What happens is if there is enough strokes, DoD will link your browser directly to the *.png file that is stored on Amazon s3, otherwise DoD will just send your browser the image as a string of base64 data. As to why it does this, I'm not entirely sure, since the amount of strokes shouldn't affect the resulting file size. (If you're interested, I made a little doobly doo where you can upload files and see the base64 code: http://asparagus.tk/b64.php )

  Is this the base64 string? Looking through the page source code, this is what it links for a non-png stored image https://doodleordie.s3.amazonaws.com/d/lkTF6Zia_/eyN3PsJdY.js it looks like information to plot each stroke. I'm not too experienced in comp. science stuff :\

  I noticed, upon inspecting the element to get to the amazonaws link for a png a while back, that some are to js files that looked like a bunch of coords for replaying strokes, so I assumed that they just changed over at one point and only older doodles embedded a png on the page. But now I see that 12 is js and 14 is png so...

  That's definitely not base64. You're probably right about it being to plot the strokes, so I may have been wrong. From the source it looks like they aren't even in <img> tags, but in <canvas> tags. I don't know html5 so I can't do much but speculate on how it works. I think the base64 comes from how Firefox handles the html5 canvas

  I distinctly noticed that only doodles with fewer strokes don't get embedded as a PNG. I've got doodles over a year old that use the js file.

  Either way, it's obvious that they had it one way and compensated for oversized images by just sending a png. But for some reason they decided to not just always send a png. I can only hope that this, and the reasoning behind it, is documented in the server side code for future generations because stop gap measures like this can cause a real maintenance nightmare.

  I'm gonna try to see if I can make a doodle with one line that has enough data that it will store as png... brb
