If you’re having problems with the way thumbnails are displayed in a viewer application, there could be a few different things going on. Here are a few potential issues that you might want to investigate:
- Image resolution: Make sure that the thumbnails you’re trying to display are of high enough resolution to look good when scaled down. If the images are too small, they may appear pixelated or blurry when enlarged.
- Image format: Some image formats may not be supported by the viewer application, which can lead to thumbnails not displaying correctly. Make sure that the images you’re trying to display are in a format that the viewer supports.
