Customize the slider of a premium Wordpress theme

Hi there, This is my site: [login to view URL] I'm using a premium Wordpress tehme named as "Newscast". I want to customize my slider. As you see there are 6 pictures in my slider. It could be at least 3 and at most 7. It's up to user. And as you see, the shrunken pictures in slider get wider from left to right when you hover the mouse over them. So you can see rest of the picture, in other words, the whole of the picture. In slider we see the pictures are leaning to the left. So we could see only the left sides of the pictures in slider when they are shrunken. Now, what I want? I want to choose the shrunken parts of every picture in slider. For example for the first picture I want to show the writing "We" clearly. For the second one I want to choose the black sheep. For the third one I want to choose th middle of picture etc. So every shrunken picture of slider should be expand from the seen part to the unseen so we could see whole of the pictures and they all should be expand discrete from each other (I think this could be difficult for you) For example first shrunken picture should get wider from left to right, the second one from right to left, the third one from middle to left and right, in a nutshell, from seen part to the unseen part. If you think you could do my project, please consider that the dimensions of shrunken part will change when I change the number of pictures in slider. It gets wider when I choose 5 instead of 6 or it gets more narow when I choose 7 instead of 6. So the frame of shrunken part should be change automatically in admin (options) panel of the theme when I change the number of pictures. So who can really do this?
