+Image generation is done by [LoremPixel](http://lorempixel.com/.  Common params are:
+
+* $dir - An absolute path to a local directory
+* $width/$height - Integer width and heigh values for the image you want generated
+* $category - May be 'abstract', 'animals','business','cats','city','food','nightlife','fashion','people','nature','sports','technics','transport'.  Singular forms of all are supported as well.
+
 ## Localization
 
 `Faker\Factory` can take a locale as an argument, to return localized data. If no localized provider is found, the factory fallbacks to the default locale (en_EN).
