Rick- I agree and that's what I'm leaning toward. The only thing I don't like is that if I want to change dimensions of all the images for some reason, I have to go back through and run everything over again. The big thing that prompted this question was that I saw .Net people using image.ashx (do a google search on it) and it seems they do it on the fly everytime. I'm not sure if .net is just better at doing it with very little overhead or if the people doing it are a timebomb waiting to explode on their server if they ever get significant traffic.

John, Since you don't want to always be resizing on the fly every time someone views an image, you might try something like this: <img src="showImage.cfm?foo=myImage.jpg"> and in showImge.cfm just use imageCFC to read the image dimensions. If the image hasn't been resized, resize it and save it back. Then use <cfcontent> to send the image. That way every time you display the image, the only added overhead would be getting the image dimensions. ALTERNATIVELY, save the resized image with a different filename like "myImage_resized.jpg" and then have showImage.cfm check for the existence of the file - if it's not there, resize the original image and save it. Then you're not even calling java to get image dimensions, you're only checking for the existence of a file with a specific name. ultimately, you're better off not doing any of this dynamic stuff cuz it won't scale. You'd be better off using some kind of event gateway directory watcher and just resizing the images as they appear. rick ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Message: http://www.houseoffusion.com/lists.cfm/link=i:4:238791 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
