Enhance SharePoint Libraries with HarePoint Thumbnails: A Quick Guide

Maximize Document Previewing in SharePoint with HarePoint Thumbnails

What it does

HarePoint Thumbnails for SharePoint generates image previews (thumbnails) for files stored in SharePoint libraries and displays them in list views, document cards, and web parts — improving visual scanning, discovery, and user experience.

Key benefits

• Faster browsing: Visual previews let users identify documents and images at a glance.
• Improved UX: Thumbnails make lists and libraries more engaging and easier to navigate.
• Support for many file types: Common office docs, PDFs, images, and some media formats.
• Server-side generation: Thumbnails are produced on the server (no client install required).
• Configurable display: Control thumbnail size, caching, and which libraries or views show previews.

Core features

• Automatic thumbnail generation for documents and images.
• Integration with SharePoint list views and custom web parts.
• Caching and storage options to reduce load and improve performance.
• Admin controls for enabling/disabling per site, library, or content type.
• Thumbnail regeneration and bulk processing options.

Typical setup steps

1. Install the HarePoint Thumbnails solution package on the SharePoint farm or tenant (follow vendor instructions).
2. Configure global settings: thumbnail size, cache path, and file-type handlers.
3. Enable thumbnails for target site collections and libraries.
4. Optionally add HarePoint web parts or modify list view layouts to include the thumbnail column.
5. Run a bulk generation pass for existing documents and verify in a few sample libraries.

Performance & best practices

• Use caching: Enable server-side caching and set an appropriate cache duration.
• Limit scope: Enable thumbnails only for libraries where previews add value.
• Monitor storage: Thumbnail images consume storage — estimate needs before bulk generation.
• Scheduled regeneration: Regenerate thumbnails during off-peak hours after major content imports.
• Security: Ensure file preview generation respects SharePoint permissions and does not expose restricted content.

Troubleshooting checklist

• Thumbnails not appearing: confirm feature enabled for the library and correct file-type handlers installed.
• Slow generation: check server resources, caching settings, and bulk processing queue.
• Missing file types: add or enable handlers for those formats per vendor docs.
• Permissions issues: verify the service account used by the solution has read access to content.

When to use it

• Large libraries with many images or mixed file types where visual identification speeds workflows.
• SharePoint sites focused on media, marketing, design, or document-heavy teams that benefit from previews.
