i need to get images from a webpage source. i can use cfhttp to load page contents

need to loop through the content to get all image url's(src)

can i use rematch() or refind() etc... and if yes how??

if im not clear i can try to clarify..

with that, once i fetch images, i just want to specify to fetch images which has image size of 800*600 only

Any idea

This should do the trick for getting the images and checking their width and height:

<cfhttp url="YOUR_URL_HERE" method="get">
<cfset images = reMatchNoCase("<img ([^>]*[^/]?)>", cfhttp.FileContent)>


<cfloop array="#images#" index="img">
	<cfset src="YOUR_URL_HERE#REReplace(img, "^.*<img[^>]+src=(['""])([^'""]+)\1[^>]*>.*$", "\2")#">
	<cfset imgInfo=ImageNew(src)>
	
	<cfif imgInfo.width EQ 800 AND imgInfo.height EQ 600>
		
		<!--- DOWNLOAD IMAGE --->
		
	</cfif>
	
</cfloop>

Ah that's ok, the URLs for the img srcs are absolute (that's bad by the way) so you need line 6 to be changed:

<cfhttp url="http://www.santabanta.com/photos/neha-dhupia/443114.htm?high=1" method="get">
<cfset images = reMatchNoCase("<img ([^>]*[^/]?)>", cfhttp.FileContent)>


<cfloop array="#images#" index="img">
	<cfset src="#REReplace(img, "^.*<img[^>]+src=(['""])([^'""]+)\1[^>]*>.*$", "\2")#">
	<cfset imgInfo=ImageNew(src)>
		
	<cfif imgInfo.width EQ 800 AND imgInfo.height EQ 600>
		
		Using cfcontent here
		
	</cfif>
	
</cfloop>
