Nodes and vector colours of a 2D picture in Blender

Question

I have a jpg picture as given below and I wanna have it entirely red with the red color having the density which would follow the original picture. A .blend file using Nodes postcomposition would help.

You can run your image into a separate RGB node and use only the red channel. This is in the material editor, but there are similar compositor nodes.
