[opencms-dev] Get image path based on downscaled image's URL

[Siegfried Ehret]

I haven't played with it yet, but the cms:device tag should help.
http://files.opencms.org/javadoc/core/org/opencms/jsp/CmsJspTagDevice.html
Types can be found here : http://files.opencms.org/javadoc/core/org/opencms/jsp/util/CmsJspDeviceSelector.html

Have fun :)
