You should put _all_ the files in bin/ that you find in the *.zip
files, not just select DLLs.
Also, the date of zlib1.dll looks old.
But I don't think these are the reasons for your problems.

What are the versions of the libraries against which the Emacs binary
was built? Look at the values of the variables libpng-version and
libjpeg-version: do they match the versions of the DLLs you installed?
(There's some explanation of this near line 200 of w32-win.el.)
