Caché DTI ContentPublisher: Tested in 7.6: Example code to fix image paths using ..UnescapeHTML() and ..EscapeURL().

image.csp

<script language="cache" method="OnPreHTTP" arguments="" returntype="%Boolean">
	
	do %response.SetHeader("Content-Type", "text/plain")
	
	quit 1 // Exit.
	
</script>

<csp:object name="gStory" classname="dt.cms.schema.CMSStory" objid="28188418">

#[ new path set path = ##class(csp.web.assets.methods.image).imageUri("990pxw", gStory) ]#

Straight out of the box:

http://www.registerguard.com#(path)#

Notice that the image URI above just downloads if you copy/paste the URI into
your browser (well, I only tested in Firefox 12/Mac).

I think that the &amp; is causing the CONTENTTYPE to not get passed to the 
StreamServer class; from what I can tell, "downloading" is the default 
functionality for the StreamServer class if it's an image without a CONTENTTYPE 
querystring parameter.

----------

Using ..UnescapeHTML():

http://www.registerguard.com#(..UnescapeHTML(path))#

The URI above will display in the browser if copy/pasted (using Firefox 12/Mac).

----------

Using ..UnescapeHTML() and ..EscapeURL():

http://www.registerguard.com#(..EscapeURL(..UnescapeHTML(path)))#

Not sure if you will need it (from my tests, it's not needed), but sometimes URL
encoding the URI/querystring (above) can help in certain situations (for 
example, if you need to put URL into another URI's querystirng).
