I don't understand why exactly, but an image saved at 2x pixels isn't necessarily 2x the bytes. Take 20 minutes and at least redo your logo and key images. He

At least in the case of 24bit PNGs, you (always) end up with 4x the pixels (2x width and 2x height) and (generally) end up with about 1.8x the size due to more efficient compression.

It's 4x the pixels and usually works out at about 1.5-2x the bytes.
