Hi Andy,

I had the same problem here a couple of weeks ago.
Assuming both your image's and gallery container's descriptions use the 
metadata element "content_description" defined in metadata set 
"silva-extra":

   You must disable the acquisition for the metadata element
   "content_description" that is used by your container.
   In ZMI, go to:
    /service_metadata/collection/silva-extra/content_description
   Set "Enable Acquisition" to "No".

If you don't use content_description metadata of silva-extra but an own 
set, you just need to do the same for your own metadata element.
