Time for action – enabling a second language
It is very simple to vary the following instructions to install whichever language you want:
Hover over the Localization tab, click on Languages, and then click on the Add new button.
Now fill the form. The name should be straightforward, for example, French, German, Swahili, or whatever.
Every country has an internationally recognized country code. To find the one for your second language, visit http://www.iso.org/iso/country_codes/. Enter this in the ISO code box.
Next, for the Flag field, browse to a graphic of the flag for that country. A handy website very helpfully makes some available here: http://www.famfamfam.com/lab/icons/flags/. Upload it and move on.
In the "No-picture" image box, you will need to provide a graphic that PrestaShop will use when no product image is available. If you always provide an image, this can be anything. If you regularly have missing pictures, a "picture coming soon" in the language you are enabling will suffice...
