Picking a custom thumbnail - FAQ, Tips
If you don’t like the default still that WOW TV picks for your video, you can change it.
Any jpg image will work, though it’s best if you use one with the same dimensions as the video, 320×240 as one example.
To change the still, click on the “Edit this video” link on the episode details page. In the edit page, click on the Version name of the video you want to add the still for (you can do it for each version).
On the right side there’s the Stills section. You’ll see the currently set thumbnail and a form. Click the browse button and navigate to the jpg on your computer. Click Open. Click Upload.
Your new thumbnail will upload and replace the old one.
If you want to go back to the WOW TV generated thumbnail, just click the Create Stills link.
