The kickstart "hand" image is definitely in there but is most likely compressed. Looking at the picture it would be a good candidate for run-length encoding and also may be coded in a lower resolution than even 320x200 (e.g. just output the same colour for two pixels instead of one). Most of the screen itself is likely to just be a background colour that doesn't require a bitmap. The bitmap itself is centred where the pic is.
