Ayuda por favor jquery

Hola tengo un gran problema ya que hace poco termine un curso de diseño web, y no tengo mucha experiencia, asi que tengo en el codigo java script que cuando se inica la pagina las imagenes que en este caso son cuadros, salen de una esquina y se centran en el medio, si pinchas cualquier cuadro se forman varios sin deshacerse y si vuelves a pinchar vuelve a su sitio, entonces me gustaria que las imagenes salieran de todos los puntos de la pagina y se formen en el centro y ese efecto que hace cuando se pincha lo haga solo al terminar de colocarse y solo una vez sin necesidad de pinchar, tambien quiero implantar de otro codigo que tengo el efecto 3d, te digo el primero que es como lo tengo y no se como mas poder cambiarlo:

now we animate the thumb to its final positions;
we also fade in its image, animate it to 115x115,

is not relevant for the first time we call disperse,
