Upload Files from web url using Coldfusion

I have been allowing user to upload file via a form online like this:

<form action="upload.htm" enctype="multipart/form-data" name="upload_form" method="post">
<input type="file" name="upfile">
<input type="submit" name="upload" value="Upload Photos">
</form>

Then on the back end the cffile would upload the file:

<cffile action="upload" destination="#currentpath#" accept="image/jpeg, image/gif, image/png" fileField="form.upfile" nameconflict="makeunique">

Now I want to do automation so that the image file does not have to be sitting in the user's computer but rather from a web destination e.g. http://www.sample.com/images/myimage.jpg instead of c:/images/myimage.jpg

I have tried this:

<cfhttp method="get" url="http://www.example.com/images/myimage.jpg"  resolveurl="Yes" throwOnError="Yes">
<cfif cfhttp.mimeType eq "image/jpeg">
    <cfset currentpath = expandpath('/test/')>
    <cffile action="upload" destination="#currentpath#" accept="image/jpeg, image/gif, image/png" fileField="#cfhttp.fileContent#" nameconflict="makeunique">
</cfif>

However, it is giving me an error:

Invalid content type: ''. The files upload action requires forms to use enctype="multipart/form-data"

I am not using a form to upload but it seems to require a form field.

So I tried this:

<cfhttp method="get" url="http://www.example.com/images/myimage.jpg"  resolveurl="Yes" throwOnError="Yes">
<cfif cfhttp.mimeType eq "image/jpeg">
    <cfset currentpath = expandpath('/test/')>
    <cffile action="write" output="#cfhttp.fileContent#"  file="#currentpath#/someimage.jpg">
</cfif>

This one writes out a "file" called someimage.jpg but the output is NOT a jpg file, but something unrecognizable. With the cffile "write", it doesn't allow to check for image type or same file name.

Any help is appreciated. Thank you in advance.

Assuming the call was successful, the current code may be retrieving and/or saving the response as text, instead of binary, which would corrupt the image. To ensure you get back a binary image, use getAsBinary="yes".

Having said that, it is simpler to save the response to a file directly within the cfhttp call:

<cfhttp url="http://www.example.com/images/myimage.jpg" 
    method="get" 
    getAsBinary="yes"
    path="#currentpath#" 
    file="someimage.jpg"
    resolveurl="Yes" 
    throwOnError="Yes" />
