im trying to make a sig for a friend. How can I add glitter text to a picture?

Go there : http://www.smiliz.fr/glitters.php

Type in your text, select the color sheme you like , click on "Mettre à jour l'aperçu" , if the result is good click on "Télécharger cette image".

And finally, go in photoshop - Import, "Video image to layers" and type a "*" in the file field - It'll show all the files on your computer in the select folder.
Select the .gif. Press ok on the next window.

Then make sure the text overlay all of your layer.

Hope you understood what I said.. Kinda confusing!

ok i can add the gif file (glitter) but now how to i add the picture?

You got photoshop cs3?
