onmouseover an image enlarges

[manata111]

Hi everyone,
I'm making a web page in dreamweaver and what i need is that when you go over some images with the mouse, another image enlarges in the upper part of the site. Is this possible in dreamweaver? How?

The problem with doing it in flash is that the web needs to be done in dreamweaver and if I just import the images in flash i would need the background to be transparent since the background of the web in dreamweaver contains an image.

What do you suggest is best to do in this case?
Thank you in advance for your help!

i dont use dreamweaver myself (trusty notepad) but i'm sure it'll help you make a javascript gallery (i.e. click on a link or image and an image elsewhere changes). Google it to find out.

If you want the image transparent for flash then either cut the excess from around the image or save it as a .png with transparency.
