ColdFusion <CFIMAGE> to the rescue!

By using <CFIMAGE>, I was able to generate thumbnails for every piece of content in under 30 seconds. To add a little variety into the mix I created five different base images named thumb1.jpg – thumb5.jpg and chose one at random for each record. As I looped through the table that contained the content records, I used the content record’s ID (an auto-generated integer) as the filename and updated the thumbnail field as I went along.

The code I used looks something like this:

	select *
	from content








	
	

	
	
	

	
		UPDATE	content
		SET	thumbnail_image='http://www.mydomain.com/images/tempthumbs/#qContent.contentID#.jpg'
		WHERE	contentID = '#contentID#'
	

The “cfset imageDrawText” line is the one that adds the text contained in the content_name column to the image. It also places the caption 5px in and 15px down from the top left corner of the image.

When the code finishes I have unique thumbnails for each piece of content.
