I had a quick look already.
28 00 00 00 = header size (40 bytes)
c0 00 00 00 = width of image (192)
2f 00 00 00 = height of image (47)
01 00 = number of planes (1)
08 00 = bits per pixel (8)
00 00 00 00
40 23 00 00 = size of the image (9024)
00 00 00 00
00 00 00 00
00 00 00 00 = number of used colours (0, meaning "use all of them")
00 00 00 00 <- end of header (40th byte)
192 (width) x 47 (height) x 1 (bytes per pixel) x 1 (planes) = 9024
Header = 40 bytes
Palette = 256 bytes (2^8 because it's 8 bits per pixel)
Size of image = 9024 bytes (from calculation above)
Total size = 9320 > 9068 bytes available data
Despite these calculations seeming to show that the image is invalid, it does
open in OpenOffice perfectly fine, leading me to wonder how they are doing
that...
