Stretching images to be an ever-growing textbox

I have fair amount of knowledge in plain HTML, and in the art area of Photoshop, but putting the two together is where it gets me...

I'm trying to make a website using photoshop slices, and I want to know if there's a way, or a certain code, that allows you to be able to make an image become a textbox that will grow depending on how much text is in the box.

I also want to know if this is possible without knocking all the other slices out of place.

Here's an early version of what my site may resemble:

Thanks for your help!

You should probably just make the area that will be the text box a non image, Like slice out the balck part and then make that just a blank area. Save the other slices, put all of them into a table and then keep them the sizes you want, then make the othe part(black area) just a text box; use CSS styles to make that area a black text area, then make it the right size using the cols and rows. It should just give you a scroll bar then when it gets more text.
