Slider sizing and image fitting


I am trying to create a slider (not full screen) to display some gallery images. I need the slider to be a set width and height so that all images are displayed without resizing. I have edited the css of the style to set it to a certain height and width and I have made the images the same width and height. However, they when I add them to the slider, the images seem stretched and too big and wont scale smaller. The slider itself also seem to ignore the css rules and make itself to whatever size I have dragged it to when I added it to the page.
I have spent 2 days now trying to get the slider to just be right - I am getting frustrated now that I cant seem to do such a simple thing.
And on anther note, is there any way of copying content from one page to another to duplicate it?

Thanks. I will grant you temp access.
