Disable thumbnail synchronization for all users

By default, image thumbnails are synchronized every 30 minutes. You can configure IXIASOFT CCMS to disable thumbnail synchronization for all users, regardless of the users' personal settings.

When thumbnails are created, they are stored on the server and become available to all users the next time their thumbnails are synchronized. For deployments with very large Content Stores, thumbnails can take a lot of space.

Note: You should make these configuration changes in the Test environment and test them before copying them to the Production environment. In a dedicated SaaS deployment, after testing the changes, ask IXIASOFT Customer Support to copy the changes to the Production environment.

In the TEXTML Administration perspective, connect to your server.
Locate the multiimage.xml file in the repository's /system/conf collection.
Check out the file and open it for editing.
Locate the <thumbnails> element and set the allowThumbnailSynchronization attribute to false.
For example:
```
...

<thumbnails defaultscale="0.5" minsize="150" maxsize="600" allowThumbnailSynchronization="false"/>
...
```
Note: If the attribute is not there, simply add it and edit the multiimage.dtd file as described below.
This attribute disables thumbnail synchronization, regardless of the users' personal settings. When <allowThumbnailSynchronization> is set to false, the Synchronize Image Thumbnails option is greyed out in the Synchronization Preferences and the following message is displayed:
```
[disabled by system administrator]
```
Save, close, and check in the file.
Inform users of the changes.
The changes will be applied automatically once users close and then reopen their IXIASOFT CCMS Desktop. Users can also apply the changes without restarting their CCMS Desktop by clicking IXIASOFT CCMS > Synchronize Configuration.
