Front end: a table with pictures and text as seen in the example image, the text must change with the user's specific language. Old posts, let's say two weeks-old posts have to be archived (to be seen in another page, with the link at the bottom of the main page). The header is intended to have some logos, titles and, most important, a searching bar that allow users to find even old posts by title or text's words.
Back end: protected by a login page (that can even have a single, not changeable user, like username:good password:dog) must allow me to add new posts, with a picture and the text variants in all different languages.
I finally ask that all the posts content must be kept in a single folder, so that i can put the backend on a different server, create new content with it and then update the content folder on the frontend server to make it visible.
