DAM for Sitecore renders seo friendly media urls.
Example of a image with the title at the end of the url.
<img src="/media/526335e8993e43bd8f158b24c678cc86/75-50036/tulips" alt="A field of tulips" />
The title at the end of the src tag, is added through this processor DFS.ContentSearch.Pipelines.GetAssetFieldValue.AppendSeo in this pipeline DFS.GetAssetFieldValue. It is possible to configure which property to append. This is done in the config file DFS.Settings.config.
<setting name="DFS.MediaUrl.AppendSeo" value="assetname" />
By default we use assetname, which is the title of the asset in Digizuite DAM. If you want to disable this, leave the value empty or remove the pipeline.
