no view of high res images

Dear developers!

After certain errors we started a new site with the YAML template
(number 32).

Now we are in trouble again, because it isn´t possible to get like in
former times the popup window with the higher resolution window.
At firefox 2.0.0.7 browser: nothing happens - not even an error message
At IE 7.0 browser: javascript error - Objekt erwartet

2 explicit errors in the log-file:

[ZMSGraphic@/biegeholz/content/e5][renderDisplaytype]: can't get
dimensions
Traceback (most recent call last):
File "/opt/zope-hosts/instance/biegeholz/Products/zms/_objtypes.py",
line 239, in renderDisplaytype
px2em = float(self.getConfProperty('ZMSGraphic.px2em',''))
ValueError: empty string for float()

[ZMSCustom@/biegeholz/content/e649/e650/e655/e656][getObjProperty]:
Can't get attribute from meta-objects: tagcloud.change_uid
Traceback (most recent call last):
File "/opt/zope-hosts/instance/biegeholz/Products/zms/_objattrs.py",
line 683, in getObjProperty
metaObjAttr = self.getMetaobjAttr( self.meta_id, key)
File
"/opt/zope-hosts/instance/biegeholz/Products/zms/_metaobjmanager.py",
line 507, in getMetaobjAttr
attrs = meta_obj['__obj_attrs__']
TypeError: unsubscriptable object

Any idea how to fix this error?

thanks a lot in advance, 
regards

Jürgen Fragner
