Dynamically resize images with ColdThumbs
Monday, March 12th, 2012
A few days ago I was coding up a WordPress theme for a client who intended to move away from WordPress.com.
One thing I noticed is that on the WordPress.com installation, images were dynamically resized by adding a parameter after the image file extension.
i.e. http://domain.com/images/an-image.jpg?w=400
Since many of the posts linked to images in this way, I had to find a way to replicate it into the WordPress installation on the local server. A quick Google search and I discovered ‘TimThumb‘, a php script for dynamically resizing images, very popular amongst WordPress theme developers.
Within a few minutes, I had the functionality I was looking for.
‘Very cool’, I thought to myself… So why can’t I do this in ColdFusion?
Enter: ColdThumbs!
Inspired by TimThumb, ColdThumbs is allows you to dynamically resize an image (local or external) to your desired dimensions.
The script will automatically create a cached version of your resized image and return the image as content.
I developed this as a bit of fun one Sunday (yeah, that’s how I roll) and have put it up as my first project on RIAForge. It’s working great for me, but I’d love to hear feedback or feature requests from anyone using it.
