store your images in a db (mysql works well) in a blob data field.

first send a header information telling browser that content is an image

header("content-type: image/gif");

then query your image

$image_content= mysql_result(mysql_query("select image_source from table where [criteria]"),0,"image_source" );

then simply print it out

print $image_content;

then flush it

flush();

thats all
