[flexcoders] Re: Can I use mx:Image to load images dynamically from an image.cfm page?
if you go to umage.cfm in a web browser does the image appear? Are you setting the ContentType header on the response correctly?

RE: [flexcoders] Re: Can I use mx:Image to load images dynamically from an image.cfm page?
Yes, I'm setting the contenttype header correctly, and when I navigate to the .cfm file in a web browser the image appears as I expect it to. When the image is originally uploaded, I'm capturing the image's mime type and storing it in the database so that I can use it for my cfcontent when retrieving it for display later. I've been using a process similar to this for 3+ years on a website without any problems, but I want to transfer the same idea to Flex now, and am only getting broken images. -Original Message- From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of lepusmars Sent: Tuesday, February 13, 2007 12:32 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: Can I use mx:Image to load images dynamically from an image.cfm page? if you go to umage.cfm in a web browser does the image appear?

Try using the cfm page's full URL as the source property, just to make sure you aren't running into a problem with relative paths. mx:Image x=0 y=0 source=http://myserver.com/image.cfm/ If that still doesn't work, you can try setting some handlers, probably on the ioError event, to see if more information on the error condition is available. --- In flexcoders@yahoogroups.com, k.hemmen [EMAIL PROTECTED] wrote: Our flex developer recently left our company, and I've been given the task of resuming work on an enormous project he was involved in.
