Anybody know of an alternative to CFX_ImageCR3 by Efflare? Efflare appears to have gone out of business and the version of CFX_ImageCR3 seems to require an ever increasing amount of memory.
Not familiar with this custom one. What did do for you / what are your requirements?
Also what version of Coldfusion you running?
I'm running CF 10.
The CFX_imageCR3 tag, allows me to create image gallery thumbnails that when clicked, pop up into a new window allow the user to click through the images.
I use it quite extensively on this site www.omhsbandboosters.org in the Photos section. Here's a link to a page that demonstrates the output http://www.omhsbandboosters.org/body.cfm?id=1164
All I have to do is create a page, using an include that references the tag, and all indicate what directory the photos are in. The code then creates the thumbnails based on whatever is put in the indicated directory.
Which OS are you using? Do you have access to the server to install third-part libraries? I've had great success with GraphicsMagick (free; Windows) and have been using it with ColdFusion 9+. It's actually faster, has better compression and is more compatible with more images than anything built into ColdFusion. Flickr & Etsy use GraphicsMagick to generate thumbnails & optimize all of their images. (NOTE: I also don't have to worry about any new bugs that get introduced with newer versions of ColdFusion.)
I've had issues with ColdFusion 8/9/10 not being able to identify/read an iPhone 4S as a "valid image". I also had many errors logged whenever clients would upload CMYK JPGs.
Here's a Custom Tag I wrote to perform many conversions (including AspectCrop like ImageUtils.CFC).
If you need to access EXIF data, EXIV2 (free; Windows) is a good, faster alternative too:
