different caption position for each image?

Hi,

Need a bit of help customizing the slider captions.

Basically i just want the caption positioned on the left side for the first image and then on the right side for the second image and so on.

i can style the caption box itself but having a hard time finding a script or a custom code to switch caption positions.

im not a programmer but i can understand a bit of php.

hope someone can help or lead me in the right direction. thanks!
