I am unable to preview images with Emacs 24.5.1 + AucTeX

installed and that their binaries appear in my PATH. What
can be the cause?

I had a similar problem and it was caused by spaces in ghostscript's
path. Try customizing the variable


using short file names to your ghostscript path. For example, I have
ghostscript in

C:\Program Files\gs\bin\gswin32c.exe

so I customized (via customize-apropos) "preview-gs-command" with a value


Try doing something similar in your case. Does that solve the problem?

No. :-( I use the 64 bit version of Ghostscript and it looks like preview.el only works with 32 bit Ghostscript.
