PNG is a file format and PNGReader implements it. Nothing crazy here.
You need to create a vtkImage and populate its data via write pointer.

I have an image (a PNG in this case but I'd like to be general here really) in memory and I'd like to use it in the normal VTK way - as if it had been read in by vtkPNGReader, for example. Is this possible? I've looked at the code for vtkPNGReader and it looks like the only way to read a PNG is from a file, which seems crazy! Have I missed something? Is there another way to do what I want?
