cheers oe,
i had tried to extract it from the red one, ( I didnt realise there was two of them) but is was a headfuck. had missed the blue one
I was having a go at the blue one when the solution came to me. convert the gif image to pdf then back to png. Now the gimp allows me to apply the full range of filters.
not the way you would expect, but you got me there
as for those other ones?
