The Collada (dae) export behaviour change (i.e. it no longer renames texture files and you can safely reload your model after any changes in SketchUp) was made in SU 8 M2 in December 2011 (right in time for Lumion 2 actually). Since then, two more Maintenance releases have been made but this function has not been touched ever since. See details here:http://support.google.com/sketchup/bin/static.py?hl=en&page=release_notes.cs
This measn, version 7 still has the undesirable "feature". Free SU users (who need to rely on the Collada export option) should upgrade to the current version 8. SU Pro users, who (for whatever reason) do not want to upgrade, could still install the free version of 8 and export from there or use the FBX export format from SU - which has never had this issue.
Edit: credits for the new exporter go to Simone NicolÃ²
who wrote it despite it was not Google's priority - or even on any agenda - to change the code.
I had a chance to personally meet him in 3D BaseCamp in October and thank him for the new exporter. Unfortunately he could not accept my invite for a beer then.
