How to hide text behind image

[lifco]

I don't think I clearly stated my question. This is what I have:I have my web template (done in photoshop) ready and set to upload to server; however, if user hides/disables images, website will be blank bc all the text is on the image itself. I have created the css layout and want to make a text version of the website, but how do I achieve this without having the text overlap the image?? I want the user to still see a text version of the website in case they disable the images on their browser.HTML CODE:\[code\]<div id="main_divs_container"> <div id="left_div"><img src="http://stackoverflow.com/questions/13875153/images/left_div.jpg" width="249" height="622" alt=""></div> <div id="index_middle_div"><img src="http://stackoverflow.com/questions/13875153/images/index_middle_div.jpg" width="488" height="622" alt=""></div> <div id="right_div"><img src="http://stackoverflow.com/questions/13875153/images/right_div.jpg" width="253" height="622" alt=""></div></div>\[/code\]
