My  next question is how do i  use the templates I downloaded supersized  but have no idea how to add my pictures or text to  it for it function like i would like it to. can any one help me? I have the entire cs3 master collection i was trying flash but someone made mention of jquery and showed me the possibilities. I was impressed he said he has been working with jquery and does not plan to use flash again.
