Uploading images & Image manipulation

Hi everyone

What I am trying to do is this:

I want to have a JSP where the user browses for an image, and then clicks a submit button, I then want the selected image to be uploaded and stored...

My questions are:

1 - Can the image be stored in a MySQL database or does it have to be uploaded to a directory

2 - Is there a way to manipulate the image and make thumbnails etc in a Servlet?

3 - Is there a java API for doing things like this (if yes any chance of a url)?

Many thanks

1) I would store the image in a directory. It makes it easier to show the image to the user (via an IMG html tag), and makes it easier to backup your data (as your database doesn't contain loads of BLOB fields)
2) Yeah, sure... Load the image in to a BufferedImage, call getScaledInstance, and write the image back out again using the JPG compression routines (http://javaalmanac.com/egs/javax.imageio/BasicImageRead.html and http://javaalmanac.com/egs/javax.imageio/JpegWrite.html)
3) See 2 ;-)

Oh, and http://javaalmanac.com/egs/java.awt.image/CreateTxImage.html for the "making it smaller" bit ;-)
