Body
This is my first bit of programming in quite a while, so I'm basically starting from scratch, and I'm using coldfusion 8. What I'm trying to do is create a series of uniform thumbnail images (always 68 X 46) from a variety of larger images, some portrait, some landscape. In both cases resizing the image to fill the height or width of the thumbnail and then cropping the excess image equally off either side (top/bottom, left/right). Just as photoshop does by default with canvas resize. The code below works really well as long as the source images dimensions/ratio is perfect, but I've started to run into cases where the code fails. In this case, when a resized images width ends up being less than 68. <pre><code><cfif FileExists(ExpandPath('images/gallery/thumbs/thm_'&imageMed[i].medium.XmlText)) IS false>  <cfif imageDataThumb.width gt imageDataThumb.height >  <cfset ImageResize(cfImageThumb,"","46")> <cfset ImageCrop(cfImageThumb,(cfImageThumb.width-68)/2,0,68,46)>  <cfimage source="#cfImageThumb#" action="write" destination="images/gallery/thumbs/thm_#imageMed[i].medium.XmlText#" overwrite="yes"> <cfelse>  <cfset ImageResize(cfImageThumb,"68","")> <cfset ImageCrop(cfImageThumb,0,(cfImageThumb.height-23)/2,68,46)>  <cfimage source="#cfImageThumb#" action="write" destination="images/gallery/thumbs/thm_#imageMed[i].medium.XmlText#" overwrite="yes"> </cfif> </code></pre> Trying to solve these "edge cases" is turning the code into a mess. Is there a better way to approach this? Something in coldfusion or a cfc?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
