various improvements on php site

two requests concerning this genealogy site: 1/ The pages of this site can be shown in four languages. Request is to offer "by default" the preferred browser langage of the visitor (see [login to view URL] ) Alternatively, and on top of it, to offer four flags to choose the language (instead of actual drop-down menu) 2/ The second request implies to show an image in the header of all pages, depending on a label appearing in the body of the page. e.g. if the label "test" appears in the body, then the photo [login to view URL] will appear in the header. So, quite easy tasks, but my knowledge of php programming is nil
