WaterMark Help?

[nokesa]

I'm fairly new to the technological aspects of photography. But I'm putting together a portfolio, slowly but surely. And I would really like to learn how to make a watermark and put it on the photo. If nothing else, It will hopefully make me look a bit more professional and as I learn more and recieve more opportunities, I can post pictures online.
So if someone could help a newbie, it would be much appreciated. I need to know how to make one and how to put it on a picture. I'd like one that "pops out" but anything would help me!

The programs I have available to me :
Photoshop 7 (I know, I'm a bit out of date)
ImageReady
Picasa 3
Windows Live

Thanks soo much for any help!

Picassa can add text... As can PS7 - you may want to design one and use photoshop to add your watermark... Lightroom has a built in Watermakr as well..

Get the program called Phatch this allows watermarking and many other actions like scaling, re-write exif, increase contrast, saturation etc it will also do this as a batch to all or some images in a folder.

VERY useful utiltiy and its free.
