How can I change the photo size dynamically from the server?
<p>I have a large number of photos on the Server. The question is I have to save the photo into every size I need. <br>
I find that many websites use the url such as <a href="http://www.abc.com/89-w100-h100.jpg" rel="nofollow">http://www.abc.com/89-w100-h100.jpg</a> to show the photo in any size. When I change w and h, I can get the photo in this size.
I just want to know how can I achieve this function.<br>
ps: I can cut the photo into the given size. But I don't know how to show the photo on the browser.<br>
Thanks in advance!</p>
