Curswine, can you answer the first topic? i'm having the same problem, when i click on upload designs it sends me to the overview of the galleries. I've tried to write the link my self but it neither works.
Not sure what the problem could be here, all I can think is that you're not logged in when you're pressing the 'upload designs' button. When I click on the 'upload designs' button I get taken to my user panel where it displays all my previously uploaded images.
If you are logged in and that still doesn't work then you can try an alternate route. Click on the 'Fantasy Kit Design' button at the top of the screen to take you to the main gallery overview, when you're there click on the 'User Panel' link which you can see just above the part that says 'TOP 40: Top Rated - Last Added - Last Commented - Most Viewed' and to the left side above 'My Favourites'.
Once you've clicked 'User Panel' you'll see the screen of all your previously uploaded work, and while you're there there is a button that says 'NEW PICTURE' in the center of the page just below the 'TOP 40' selections, it's grey so it's not exactly the easiest thing to see. Once you click that you'll be taken to a page to upload your image.
Remember to do all this while logged in though.
