No Cache Configuration for ImageDetailsDto

There is no cache configuration for the ImageDetailsDto so it logs the following errors for ehcache

2010-02-19 15:08:44,633 WARN [main] [sf.hibernate.cache.EhCacheProvider] buildCache Could not find configuration [com.atlassian.confluence.pages.attachments.ImageDetailsDto]; using defaults.

Its not a huge problem because both ehcache and coherence create a cache anyway, but we should fix this up since it causes a fair amount of log spam.
