save as _> unable to retrieve the file_name of the image

Hi there. I wonder if anyone know why i cannot retrieve the file name of an image file when i get the image from a datbase. I have an image stored in the database(mysql) and i also store its filename when uploaded. However when i ouput the file on the website and somone wants to save this image --- It says filename: outputting the .php file name as the name for all the pictures. I hope you understand me . Eg. When i click on save image as ---> The file seems to be given a default name of "whatever the outputted .php file is called " eg. onearticle.php becomes onearticle Lars Eirik
