Php-upload-programm

yesterday i started writing a little program, which uploads files (till now pics prefered) to the folder, which contains the PHP-file.
on the first page, u select the file u want to upload, and may enter a Title( in order to enable a gallery-database with my-sql);
second page shows u wether the data has been sent to the database([COLOR=Red]THIS IS THE MAIN PROBLEM because it wont save anything to the database[/COLOR]), info about the file, where its gonna be saved, or if a file(pic) alrady exists with the same name, in this case the script should view the “new-version”(which cant be uploaded) and the “old-version”(which alrady exists"[COLOR=Red]but problem is, it wont show the already existing file
[COLOR=Black]here are the two scripts, and css(in order u need to see more)
FIRST FILE,
