Adding photos to Mysql database

How would you go about getting the name of each photo so it can be added to a mysql database? I know how to add single items from a form into a mysql database, but I'm not sure how it would work with the "for" loop you have.

Not working with transparency

it doesn't work for images with transparency, it becomes black :(

MySQL integration....

I have a question about integrating this with mysql, for some reason the upload works but the insert into query is not.
Where should the insert query be called in this script? I have it run where the foreach($_FILES as $k .... is

I am sure it is an easy fix, but this one has me stumped.
