# Miscellaneous

Under **Settings → Application Settings → Miscellaneous,** admins can configure core behaviors for image rendering, sharing permissions, and CDN usage. These settings can improve performance, control user access, and define how shared content is handled.

### **CDN**

**Use Internal vs External CDN for storing images**

* **Internal**: Images generated by Tellius (e.g., charts) are stored within the internal server infrastructure.
* **External**: Images are stored externally (e.g., in an Amazon S3 bucket or a similar CDN) for faster access and better scalability. Recommended when embedding or sharing content across users.

### **Collaboration**

**Minimum effective role required for sharing**

* Controls which users can share content (e.g., charts, reports) via public links or CDN-hosted images.
* Select a minimum role and any user with a role **below** the selected role **cannot** share content externally.

### **Report Configuration**

**Offline Render:** If enabled, rendering is done without requiring live access. Useful for scheduled jobs, exports, or PDF generation from backend services.

**Public URL:** The URL used by external users or services to access shared or rendered content from Tellius. Click on **Update** to apply changes.

**Internal URL:** Internal-facing service endpoint used for rendering within Tellius. Click on **Update** to apply changes.
