- .jpg files are displayed correctly in both Workspace and Classic UI as preview
- .jpeg files are not previewed (in Workspace) and also not in Classic UI -> additionaly I need to download it and then see the image
Could someone help what could be issue?

Hi @sn-ushi
1. Check the glide.attachment.extensions system property to ensure .jpeg are not restricted
2. Navigate to System Properties > Document Viewer.
Ensure the property com.snc.documentviewer.enable_document_viewer is set to true.
