How to disable thumbnail generation in alfresco

I have an alfresco 3.4.d instance that seems to have a problem with content transformation while trying to generate thumbnails for PDF.

Is there a fast way to disable thumbnail generation in order to confirm my suspicions?

Solution

To disable the Share thumbnails generation, you can set the following property in alfresco-global.properties:

system.thumbnail.generate=false

You can also turn off selected mimetype thumbnail generation using the mimetypeMaxSourceSizeKBytes property. If the value (KB) is less than zero, a thumbnail will be generated regardless of size. A value of 0 turns off thumbnail generation for a given mimetype.

You can check here too :

### Thumbnail maximum size limits (KB)
###
system.thumbnail.mimetype.maxSourceSizeKBytes.pdf=-1
system.thumbnail.mimetype.maxSourceSizeKBytes.txt=-1
system.thumbnail.mimetype.maxSourceSizeKBytes.docx=-1
system.thumbnail.mimetype.maxSourceSizeKBytes.xlsx=0
system.thumbnail.mimetype.maxSourceSizeKBytes.pptx=0
system.thumbnail.mimetype.maxSourceSizeKBytes.odt=0
system.thumbnail.mimetype.maxSourceSizeKBytes.ods=0
system.thumbnail.mimetype.maxSourceSizeKBytes.odp=0
