The Sources panel sits along the bottom of OBS. Click the + button in its toolbar and choose Browser from the list.
2 Name it and click OK
Keep Create new selected, give it a name you'll recognize, and click OK.
3 Paste your link, set the size
Paste your overlay link into URL, then set Width and Height to the size your editor shows next to the link (most overlays use 1920 × 1080). Click OK, the overlay appears in your scene.
✓ Good to know
Drag to position. Click the overlay in your scene and drag it wherever you like; corner handles resize it.
Changed your settings? Some overlays carry settings inside the link itself. If your editor says to re-copy the link, paste the fresh one over the old URL in the source's properties.
Overlay looks stuck? Open the source's properties and click Refresh cache of current page, or hide and re-show the source.
Looks cut off or small? Double-check Width × Height match the size your editor recommends.
