If the default language was changed in the web.config file, when you search in the Select Media dialog box, you might get the following message:

No items are found.

The log might contain the following  error:

Solution

To resolve this issue, add a version in the default language, for example, nl-NL, to the /sitecore/system/Settings/Buckets/Search Types
item in the Master database.
