When viewing a node (Full view) with admin2 design, the children will be fetched and shown.
For that ezpublish tries to generate thumbnail-previews if the object has an ezimage-attribute.
if the ezimage-attribute is not filled/used the following errors occurs for each ezimage attribute.

[ Jul 14 2011 16:19:52 ] [127.0.0.1] Timing Point: Module start 'ezjscore'
[ Jul 14 2011 16:19:52 ] [127.0.0.1] eZImageManager::createImageAlias:
The reference alias original file does not exist
[ Jul 14 2011 16:19:52 ] [127.0.0.1] :
Original alias does not exist, cannot create other aliases without it
[ Jul 14 2011 16:19:52 ] [127.0.0.1] eZImageManager::createImageAlias:
Failed creating the referenced alias reference, cannot create alias small

I investigated that problem and found out that ezjscAjaxContent::simplify forget to check, if the image-attribute is filled.

I created a patch. Please verify my attached patch.

a node whose childrren has image attributes

Steps to reproduce

1. Create an image without filling the ezimage attribute
2. node/view/full the parent node
3. view the error.log
