Follow these steps to change the number of images displayed automatically when opening the DICOM viewer.
Managing Default Series Layouts
When posting a study with 6 or more series, the default layout in both the draft view and the DICOM viewer is set to a 2x3 viewport layout grid. Each series uploaded creates

a single key image in the Draft as a preview. The location of the series in the viewer is represented by a red square on the grid layout, and you can drag and drop images to arrange them into your preferred default viewport locations.

Adjusting the Layouts:
-
The viewer automatically selects a layout based on the number of series in the study.
-
To reduce the default layout (e.g., from 2x3 to 2x2, 1x3, 1x2, or 1x1), use the Bin icon to remove key images until the layout switches to a simpler layout.
-
Removing images in this view does not affect the original series or DICOM study. At this stage, no series or images can be permanently deleted from the viewer.

💡 Tip: Simplifying Layouts in Studies with Many Series
If a large case includes many series and generates many key images, it may make it difficult to manage the default layout like a smaller study.
-
A tip to manage this is to delete all key images
, leaving only one.
-
Then, go to Recover images and select only the key images for your 6 preferred
series to restore. This gives you control over the layout and makes arranging easier before saving your draft.
Troubleshooting
🔄 If the key images in a large case become unresponsive, try saving your draft and refreshing your browser link to resolve the issue.
