CW Image Optimizer
Let's solve this once and for all (2 posts)

    The well known error: CW Image Optimizer requires littleutils. You are missing: opt-png, opt-jpg, opt-gif.
    I have Ubuntu 12.04 64bit, nginx, php5-fpm, mysql, phpmyadmin, fail2ban, postfix, littleutils 1.0.29.
    I've installed littleutils as instructed.
    Installation was successful, the only error i saw was:
    gifsicle utility missing: skipping opt-gif
    pngcrush utility missing: skipping opt-png

    Although gifsicle and pngcrush are installed:
    libjpeg-progs is already the newest version.
    libpng12-0 is already the newest version.
    libpng12-dev is already the newest version.
    gifsicle is already the newest version.
    lzip is already the newest version.
    p7zip-full is already the newest version.
    pngcrush is already the newest version.

    Symbolic links are there:
    ln: failed to create symbolic link `/usr/bin/opt-jpg': File exists

    Trying to opt-jpg via ssh fails:
    opt-jpg warning: http://static.mujo.ro/2013/07/iulie-2013-concurs.jpg is not a writeable non-directory file

    Media Gallery folders have 775, files 664.

    Clicking "skip littleutils check" throws "Bad response from optimizer" error.

    So, what is the problem?

    Could it be a user issue? On a previous server processes ran as www-data (CW plugin worked) but now are running as "username" (CW plugin not working).

    How can this be solved?

    Thank you.

    I am having a similar problem.

    The installation worked like a charm on my dev VM, however once it moved to test I get this on the test environment:

    CW Image Optimizer requires littleutils. You are missing: opt-png, opt-gif.

    There is no sign of opt-png or opt-gif in my /usr/bin directory.

    How can I install these independently?
