comment How many times can I open and resave a jpeg until its quality noticeably drops?
If you have a good enough display and eyesight, once.

comment Is there a name for a Wikipedia-like “W”?
You may already know this, but just for completeness, let me note that the specific font originally used in the Wikipedia logo was Hoefler Text, although it was later changed to Linux Libertine, with a special variant glyph for the W.

comment How to make PNG-quality animations in GIF format?
Also note that a 30 fps frame rate is high enough that at least some versions of IE will not run that animation at its intended speed. It may not matter much in this case, but if you need to ensure a consistent animation speed between browsers, the highest safe frame rate appears to be 16.67 fps (= 60 ms frame delay).

comment How to make PNG-quality animations in GIF format?
One more detail to note is that each frame in a GIF animation can have it own separate 256-color palette. One way to make use of that feature is that, if the color scheme in your animation changes halfway through, like in the example animation linked above, you could prepare the segments of the animation separately and then join them together using a GIF processor like GIFsicle.

comment BW image - make all black areas blue?
That does seem like a good reason, and may even legally qualify as a valid signature. (I'm not a lawyer, but AFAIK, the law in most places tends to follow the principle that if you call something your signature, it is your signature.) Still, my warning stands: if the place you're sending this to is nitpicky enough to have already rejected one form for an "invalid signature", there's no guarantee that they'll accept a re-colored one either. A printed picture of a signature just won't look quite the same as a handwritten one, at least not unless you use a really high-quality printer.

comment BW image - make all black areas blue?
@user23122: Why not just sign the form by hand? Or are you trying to forge someone else's signature? If so, please do note that a) this is dishonest, and possibly illegal, and b) no matter what you do, the recipient can probably tell a printed signature from a handwritten one, if they look closely.

comment Problems with Inkscape's trace bitmap when converting with multiple colors
@DA01: The tracer, in effect, quantizes the colors anyway -- it's not smart enough to extract additional contour information from anti-aliasing. You can sometimes recover some of the lost detail by scaling up your image (say, by a factor of 2 or 3) before quantizing it (and perhaps using a small amount of Unsharp Mask to sharpen the edges blurred by the scaling). In any case, however, you'll most likely need to tweak some of the edge pixels by hand in your raster editor (PS / GIMP / etc.), as there will likely still be some stray pixels of intermediate colors along edges that should be sharp.

comment Winter Bash 2014 Graphic Design
The snow animation used on the Winter Bash home page is actually a rather fancy custom-written one by balpha; see meta.stackexchange.com/questions/213043/… and blog.stackoverflow.com/2014/12/winter-bash-2014. Relevant quote from the 2014 blog post: "Management gave us a clear mandate when it came to building new features into Winter Bash: We were not allowed to spend weeks on snow animation."

comment Making backgrounds of animated GIF files transparent
Hmm... have you tried using the command prompt and specifying the full path to the gifsicle.exe? Or cd-ing to the folder you installed gifsicle into, and running the command from there? Or adding that folder into your %PATH%?
