Detailed Description

Loads a thumbnail for the given request. Thumbnail candidates are JPEG files that are either TSK_WEB_DOWNLOAD or TSK_WEB_CACHE artifacts. JPEG files are sorted by most recent if sourced from TSK_WEB_DOWNLOADs. JPEG files are sorted by size if sourced from TSK_WEB_CACHE artifacts. Artifacts are first loaded from the DomainSearchArtifactsCache and then further analyzed.
