RE: retrieve remote images using cfhttp?
All CFHTTP does with an action of GET is execute the page specified in the URL and return the contents to a variable. You can output this content and it will look as if you had gone to that page, but you cannot just grab files (physically) from another machine using this method. In order to do that you would need cooperation from whoever you want to take files from; they would have to make a site that you can hit that would send you files, but that is a whole other issue entirely:) Good luck!

Re: retrieve remote images using cfhttp?
You are thinking too hard. If you want to display that image, just use a normal image tag... img src="http://www.lexus.com/images/home/mn_ph_sc_top.jpg" . . . No ColdFusion required.

RE: retrieve remote images using cfhttp?
i have been trying for the better part of the morning to figure out where i am going wrong with the CFHTTP tag. i get a list of about 200 cars two times a week and the majority have photos (with full url to other sites) but cant seem to figure out how to get CFHTTP to download an image off of a remote site and save it locally to my hard drive. You're grabbing raw binary data here (the contents of the jpeg), not text. Try using notepad to open an image on your local machine. You'll probably see the same thing. You could try saving the variable as a file to your hard drive. That might work. Probably not though. I haven't tried that in ages but as I recall CF had issues with the NULLs (the 0's) in such variables and wouldn't properly address the entire contents. That may have been fixed in cf4.5. Not sure as I generally use a COM I wrote called TCPClient to do all my CFHTTP-like work. I specifically make the COM so it could grab and save binary data like images. :) --min ~~ Structure your ColdFusion code with Fusebox.
