Apply .png or .jpg onto mesh

Hello,
my client wants his brand logo applied on a mesh. Is there any possibility how I can project it on it. Already tried it via Decal but didnt work out so well, bc wasnt visible on the mesh.

Hello - does any texture appear on the mesh? it may have no texture coordinates - can you post here, or send the mesh to tech@mcneel.com, with a link back here.
