  1. fixed version number

  2. Clarified instructions further

    For the best reliability, the JS needs to be the first JS on the page.
    Not *just* in the <head>, but as high up as you can put it.
  3. Updated changelog


    Now generates Retina images correctly if the required image size was
    larger than the maximum $resolutions value

  6. Smarter handling of Retina type displays

    Previous AI behaviour meant that supporting Retina required adding very
    high values in the $resolutions array. This is sub-optimal:
    1) This array is meant to be nothing more than the same values as your
    media query breakpoints. Adding larger ones isn't intuitive.
    2) When no cookie is set, AI sends non-mobile devices the largest
    $resolution value, which in this case could be far too large for most
    AI is now much smarter, you do not need to edit the $resolutions array;
    just leave that as your CSS MQ sizes.
    AI now auto-detects the pixel density of any high DPI device and either
    picks a matching size from the existing array, or creates new high-dpi
    images which are multiples of your chosen $resolutions values.
    NOTE: If you see folders in the ai-cache directory which are *larger*
    than any defined in your $resolutions array, it is because someone with
    a high DPI / Retina display visited your site, and AI was able to
    generate the required image.

  1. Improved mobile detection. Better first-run experience

    Better behaviour when cookies are not available.
    Now creates the cache directory itself, making installation a two-step
    1) Put the files on your server
    2) Add one line of JS to the <head> of your HTML

    If you want to treat Opera Mobile as a mobile browser too, change the detection to "mobi" instead of "mobile".

  1. Bugfix

    Eliminated occasional double-slash in $cache_file path due to
    $requested_uri sometimes starting with a /

  1. Bumping the version number

    No actual changes, I'd just forgotten to update the version number in
    the comments last time.

  1. Added note to security conscious people

    Advised the very paranoid to move ai-cache outside of web-root.
  2. Recommend 755 permissions, not 777

    777 is dangerous as potentially anyone could write and execute files.
    Use 755 if you can. Or, set the ai-cache directory to be outside of
    your web-root.

  2. Bugfix. Also re-instated $mobile_first as TRUE

    Stupid mistake was causing the browser detect to always return false.
    Now fixed.
    With this update Adaptive Images now detects if a user is running on a
    desktop OS and switches $mobile_first to FALSE in that case. This means
    that _if no cookie is set_ and $mobile_first is TRUE the following will
    On a mobile phone, the mobile sized image will be delivered.
    On a desktop, the highest resolution configured will be delivered.
    If a cookie is set, Adaptive Images will use the cookie value to
    determine the correct size image to send.

  2. Make $mobile_first safer

    To work around browser issues with unreliable cookie setting speed
    Adaptive Images now also checks the user agent string.
    If a desktop environment is detected, $mobile_first is automatically
    over-ridden to "FALSE". If not Adaptive Images will obey the configured
    This is a safety fallback and requires testing before I revert the
    default $mobile_first configured value to TRUE.
  3. Fix rare GD lib bug

    Fixed an issue where GD was present but did not always have the
    imageconvolution function available.
    Changed $mobile_first default to FALSE to avoid issues with
    unpredictable browser behaviour relating to race conditions between
    cookie setting and image requesting
