Find a image, do a action.

Hi. Im very bad at scripting, thats why im here writing. Im trying to make a script find a image, when that image is found it should perform a rightclick action and wait 0.5sec. Then perform a rightclick action again and loop. So, find image - rightclick - wait 0.5s - rightclick - loop. Ive been looking all over here but still dont understand. As i said im bad at this. Thanks for the help in advance.
