Magic Zoom use Extended image variable as MZ Large Image

[graphicz]

Has anyone used the variable <Actinic:Variable Name="ExtendedInfoImage"/> to define Magic Zoom MZLargeImage1?

[NormanRouxel]

It's better to use <actinic:variable name="ExtendedInfoImageFileNameRaw" /> as there are bugs in the way ExtendedInfoImage is implemented.

Can this be defined centrally?
Site has many products with large extended info images.
Magic zoom retrofitted by client.
It would be nice to define MZLargeImage as <actinic:variable name="ExtendedInfoImageFileNameRaw" /> to save trawling through the site changing product by product.
Changing the MZLargeImage variable to text and using <actinic:variable name="ExtendedInfoImageFileNameRaw" /> as default value didn't work.
Thanks

Cracked it!

Enable Magic Zoom globally in site options.

In design, library, layouts, Magic Zoom Main Image.
Open layout Magic Zoom Main Image.

Change line 11 from:

<a href="<actinic:variable name="MZLargeImage1" />" id="zoom<actinic:variable name="ProductID" />" class="MagicZoom MagicThumb" rel="zoom-position: <actinic:variable name="MagicZoomWindowPos" />">"<img src="<actinic:variable name="ProductImageFileName" />" border="0"/></a>

to:

<a href="<actinic:variable name="ExtendedInfoImageFileNameRaw" />" id="zoom<actinic:variable name="ProductID" />" class="MagicZoom MagicThumb" rel="zoom-position: <actinic:variable name="MagicZoomWindowPos" />">"<img src="<actinic:variable name="ProductImageFileName" />" border="0"/></a>

Thanks to Norman.

Thanks to both of you, but any suggestions on how to change the 'default standard image' to the extended info image (rather then the general image)?
I am having a hard time installing magic zoom on my site. I want it to function on my extended info pages (so installed the layouts on this page) but cannot achieve the look as advertised with the motorbikes (http://ee-scape.com/acatalog/Magic_Zoom.html) Here is the link to my original page that I want MZ to work on: http://www.janeaustengiftshop.co.uk/...en-centre.html (ie. One large image, four small thumbnails beneath, all clickable and zoomable - just like the motorbikes)
I have opened a support query but just in case anyone has cracked it I'd love to hear from you. It is probably glaringly obvious but I cannot get it to work! Knowing how to change the standard image to be the extended info image would be a big step in the right direction!
Many thanks
