I might have misinterpreted what you wrote so far, but if your executable links only against liba and only uses symbols from liba then indeed you won't need to link against libpng. However the linker errors you posted initially indicated otherwise, since the linker seemed to need libpng symbols when linking your executable. This means one of the object files or static libraries of your executable uses symbols from libpng, which means the executable needs to link against libpng.
