(only joking Grazey .. you'd have to debug it to work with >1MB ;-0 )
Didn't someone other than Paulo Simoes do demos of overscan/Spectrum 512 pictures - well, other than just displaying them?
All my demo disks were loaned as test material a few years ago to Makedisk author .. so can't remember everyone I ever had.

- slowly digging up the bits from my past (and re-working a few): Atari ST, Sega 8-bit (game hacks) and NDS (Music ripping guide).
I develop a free Word (for Windows) add-in that's available for Word 2007 upwards. It's a fix-it toolbox that will allow power Word users to fix document errors. You can find it at: http://www.mikestoolbox.co.uk
