Decals

Hi guys,

I need some standard decals for danger warnings (I can't seem toattach an example, but its those small yellow triangles with blackedges with all kinds of drawings in them)
I tried scanning the actual stickers but this doesn't give theresult I had hoped for (I can't easily delete the white edges)

Does anyone know a website from which i can download these.

thanks a lot,
