💡 FAQ
How are thumbnails generated in Showell?
Thumbnails are automatically created when you upload content. For documents and images, the thumbnail is taken from the center of the file. For videos, it is captured from a frame slightly into the video to avoid blank starting screens.
- When you update a file, its thumbnail is automatically refreshed.
- Folder thumbnails are based on the first item inside the folder.
- If you manually set a thumbnail, it will no longer update automatically.
- Web links do not generate thumbnails, as website content can change frequently and may result in outdated or unclear previews.
What is an ideal size and format for custom made thumbnails?
Ideally, you'd like to upload your thumbnails in JPG or PNG with 500x500 pixels. For easy access, you can upload these to your thumbnail folder inside your Application Resources. This way, they will appear in your Thumbnail gallery.
