[michel111]

can anyone tell me I'm learning html,css,php to make a web page to upload images like in the web tutorial, why can't I see any tutorial on how to create the effect of moving the img src and <img src=> into the html form contains images for people to get the code to upload to the web, like the form in imageshack.us,photobucket,tinypic etcvvvvvvvvv.Ah, can I ask if css3 can make other images run back and forth besides a square running back and forth, thank
