thumbnail at Extensions

Hi,

can anyone please tell me how I can add the thumbnail.

Here is a sample of what I mean:

Thanks for your help!

does anyone know?

I only just figured this out myself - then I remembered seeing this Topic

Here goes;

When creating a new Extension Listing - you get to the part where you are uploading photos - in the thumbnailed list of uploaded photos (on right) there is an even smaller 'o' icon in the upper left of each photo. Click it to make that photo your Extensions' Thumbnail.

Now if I can only figure out how to speed up the approval process ... I'd be golden.
