Odd 404 error...
I track my 404's in an error log, and for some reason the Bg.jpg for my site comes up as a 404 often - any idea about why this is and how/if i can fix it? Maybe a php file that keeps trying to get the image if its locked somehow... I don't even have an idea...

That's the size the consortium chose for the cosine transform (CST) system. Once you get down into the nitty-gritty of the standards you'd understand.. I'll try to explain. The average picture doesn't change a whole lot over an 8x8 area. Therefore, if you are converting the bitmap data into a math equation describing the wavelength changes in the various directions possible through the block, it becomes a simpler equation. The more compression you ask for, the more basic the equation becomes too. This is why data is lost.
12K for a 4x4 image is huge. Fully uncompressed into memory, that image should only consume at most 64 bytes. That's with storing 32-bit values for each pixel and memory padding. Even a 8x8 fully uncompressed will consume 256 bytes with memory padding.
