Resizing Images Dynamically

[Confused!]

Hey everyone,

I need help on how to resize an image to a specified width. Normally I would
use something like...

<cfoutput><img src="user_files/#user_name#/images/#user_image#.gif"
width="150" alt="#user_name#" /></cfoutput>

This would indeed achieve my width attribute, BUT it would throw the image out
of proportion. Is there any way I can set the width to 150px and then
proportionally set the height attribute too?

For example, the template recieves the link for the image which is 200px by
300px...the width would be 150px, so I take 50px off that but then the height
would have to be calculated resulting in 250px.

Anyone have any ideas on how to do this?

Many thanks in advance!!

When you manually fix the width and/or height attributes of the <img> tag, all
you're doing is displaying the full-size image within the boundaries you've
specified.

If you want to actually alter the file's size or create a copy as a thumbnail,
it gets more involved. For instance, you can call standard java libraries to
manipulate the image or you can use the

Thanks, Manace.

I was looking for something like this and somehow missed Alagad.
