I am looking for a schematic of the world (not as a globe) with at
least North America and Europe on it. It should be at least 300px
wide, bigger is better. The coloring of the continents should be
uniform.
There should not be any writing or other distractions in it, just the
continents. To give you an idea, some like www.canon.com has in the
upper right would be great, just bigger and in one piece.

Hi,

I have found several of such images. Each of the following is at least
300 pixels wide:

Search strategy:
Google Image Search: world
Google Image Search: continents

I hope you have enough information. If you need any more, please ask
for a clarification!

Thank you,

Great, especially the first picture, that will be most likely the one
I will use. Thanks a lot :)

That first one seems to put the border between Europe and Asia in the
wrong place.  Russia straddles both, but is implied on that map as
being entirely in Europe.
