The only steadfast conclusion that can be drawn from image compression is that BMP should be outlawed.
RLE-compressed BMP makes for reasonably small images if the source has large areas of solid color.Okay.
Uncompressed BMP, then. And if you RLE a BMP, why not go with PNG or GIF right off the bat?

The ripple flash file is interesting. I wonder how difficult it would be to get the image out if the file weren't passed as a parameter to the flash program (ie, if the image were embedded in the flash program.
I imagine someone could print screen multiple times and piece the image together, and if they were meticulous enough they could get an exact replica...but at least it's more work than using a firefox plugin. Alternatively, they could decompile the flash program and find the image data, but I have no knowledge of flash decompilation.

Two screenshots would be enough to reconstruct the image, and it's simple enough: construct an identical gradient in the image editor, subtract it from the original, and repeat with a second shot to fill in the black bars. Decompiling flash to extract an embedded JPEG is also easy: there are programs out there to do it for you.

I have a command line tool installed (swfextract - part of swftools) that can pull images and other embedded stuff out of Flash files fairly easily. It's handy to have around sometimes.

You don't even need to create a copy of the gradient: it's already present at the sides of the image. Overlay that, Difference it, Invert the whole, and the combine the two images with Darken or Multiply.
The text is another beast, though.
