How do I fix this background problem?

I've followed the instructions for the top-down shooter to add the background but used my own image instead, and I got this:

<img src="http://www3.picturepush.com/photo/a/8400686/640/8400686.png" border="0" />

I checked the picture in Paint, and it had no white boarders. It is a PNG. Any help is very welcome, and I'm sorry if this is the wrong forum.

Is there blank space in your image? Sure looks like there is. Doesn't matter of its not white, if its clear it will still take up space in the tiling and create these gaps.

hmm click on edit animation and edit the blank space if there isn't you can change it with photoshop or use the double arrows in edit animation and put it in corner and take the space you want like 200x200 and it will fix if you didn't understand upload the capx and ill fix it

QueenOfRats, Upload a capx with the background.

Okay, here's the link:

By the way, could you tell me what I did wrong? I tried the other solutions, but they didn't seem to work. Thank-you.

Looks fine here. I'd guess it's a graphics driver issue. Does it look ok when you preview?

Okay, it looks fine when I preview. I'll try updating my graphic drivers.

EDIT: Hasn't fixed the problem. It looks fine in the preview, but in the console I get the gaps.

EDIT 2: I tried it on a much more powerful PC (so far I had been trying on a netbook) with the same image and it displayed in the console perfectly.
