How to disable thumbnail generation?

[soulpower]

Hi,

I got some problems with this issue: http://issues.alfresco.com/jira/browse/ALF-9688.
That is, Share "locks" documents while previews/thumbnails are generated, so any attempt to update the node in the meanwhile results in permission errors.
Actually, I don't need thumbnails because I've built my own UI. So is there a way to disable the thumbnail generation?
This guy solved commenting out the PDF file type in mimetype-map.xml, but obviously this does not apply to every file type. I would prefer a more elegant solution.

Thanks,
Roberto

I tried to disable the thumbnail generation adding this line to alfresco-global.properties

system.thumbnail.generate=false‍

I found this in http://wiki.alfresco.com/wiki/Optional_Thumbnail_Creation

I restarted the service, but the thumbnails are still being created for all kind of files.
I also tried to add

system.thumbnail.mimetype.maxSourceSizeKBytes.pdf=0‍

but it also didn't change anything.

I'm using community 4.0.d

soulpower, have you figured out how to disable this?

Thanks
