Uploading images into the gallery

since I had to buy credits anyway, I decided to spend some on the gallery. I now have 250 MB for one month. I activated the gallery widget and it appears as expected on the site. But how do I upload pictures into it?

FF

I'm sorry but can you try explaining more clearly?

there's a littly button where you can upload a pictures on it..

Yea, click on the "Upload picture" thing.

I expected as much but cant see that button anywhere lol
Here's a SS: The gallery is to the right, but only the widget title appears there. I set permissions for everyone to see it and use it, though no button appears. I bought credits to have a 250MB storage. Please tell me what I am doing wrong here.

EDIT:
Seems the SS turns out smaller and not showing the important part.

Here's the link, see for yourself. www.reavers.forumotion.com
Click 'home' to get to the page I was trying to SS

Just crossed my mind: Do I also have to buy credits for Gallery time? Haven't done so yet, would this be the reason it doesn't show up?

Sorted.
