Half width slider/ images

Hi,

Is anyone able to help me out with the half width slider and images?

I have responsive DT 6.5.6

I like the halfwidth slider with the text boxes on the side.

I am getting really frustrated with images sizes though.

Ive attached what mine looks like.

You can see the sliding pic doesnt expand to the size of the box, on the left, and then on the right hand side of the box, the images are too big and one of them repeats.

Can anyone answer why it does this? Is it the size of the file Im uploading? As in, do they all need to be the same mega pixle before upload?

Also, is there any way to change the colour of the text on the right?

ANY help or even a link to instructions would be ace!

Ive searched the forums for hours and there are no instructions, it seems to be you know how to do this stuff by having experience and as Im a newbie any tips without sarcasm would be great. Thanks heaps!
