Magento 1.9

Hi,

I recommend to use the PHP script, even for Magento 1.9 as it has the same option and and even more efficient regarding compression. The magento module is used by customers that already had installed this version. If you want to try it anyway, you can find it in the archive:

Good day. Tried to install the plugin to magento 1.9 according to your instructions. The link does not work,Extension page: http://www.magentocommerce.com/magento-connect/imagerecycle-image-pdf-optimize.html
redirects to the magento 2 https://marketplace.magento.com/

Hi,

There's a legacy Magento 1.9 plugin available, see:

But I recommend to use the PHP script, even for Magento 1.9 as it has the same option and and even more efficient regarding compression.
