image size is dismatch in jsp and jpg which java made

this is my java code to create image:

image = new BufferedImage(500, 300, 1);

.......

then generate jpg file

my jsp content:

<img border=0 height=300 src="../../images/W30_2_0010.jpg" width=500>

but the image show on browser is smaller than the size I set in jsp

Why?
