How do I remove subdivisions?

I’ve subdivided a mesh plane face to allow a curve modifier to do it’s thing on it, but I’m now trying to add an image texture. I’ve worked out how to add the image texture, but instead of applying one image to the entire surface, it renders the image for each subdivision.

What I want to do is remove the subdivisions so that I can add the image, and then apply the subdivisions again, but I can’t work out how to remove the subdivisions.

Does anyone know how to do this?

Alternatively, is there a way that I can render the image once for the entire face rather than for each sub division?
