how to solve this this image size problem?

i have been trying to create a page that has a links section on the left.the way i want the links to appear is displayed on this page on the net.

http://www.takethefamily.com/

if you look across the top of this page there is a welcome message followed by four sections in the shape of rectangles with blue border and with rounded corners with one sections having the text "explore our worldwide destinations by area or type of holiday..." acting as a link under the image of a world map.the other 3 sections also have links.i also want to create this kind of shapes to hold the data extracted from a database.i m not sure whether these 4 are infact images displaying the data extracted from the database.if i create such an image (simply a rectangle shape with rounded corners as i understand as an idiot) its height & width will be fixed.but it there is more data to be displayed depending upon the sql query's result.i want it to resize itself (but keep the rounded or curved corners) in terms of height & width.can any one give me some suggestions or tutorials on the net that address this issue.i m sorry i m quite new to php and web development so any help would be largely appreciated.thanks...

just to let u know that i m using php and access and iis as the server.

Well, the fact that you can highlight the text means the text isn't images. Just the rounded corners are.

As to how to do that, Google is your friend.
