The process is simple as:
– Parse/scrape sex.com looking for pictures urls based on keyword or categories
– Check that the filename has not already been downloaded(no doble post)
– Take the content of the url and store it locally as an image.
– Post it on your blog ,you must able to chose the category where to post it (I think WP should provide the needed functions)
– Must copy the title of the image,tags, and set the image as featured
It can be a boot or a wordpress plugin
