How do I make a tiled background

I'm following the platform tutorial and trying to make my own tiled background. The only problem is after I upload it there's a whitespace between each tile, how do I get rid of that?

Are you sure you're not leaving some white pixels at the border of your tile? Check again. Itś a very common mistake.

Actually the white space was only the layout background, but still there are spaces between each tile.

I'm not sure I'm getting the problem. The image in a tiled background will repeat itself seamlessly, thus, if the tiles connect well, it should show ok. Can you send the image you're using as tile?

Here ya go, it's nothing fancy just trying to learn how this stuff works.

Here what it looks like when I make it a tiled background.

Seems to work fine here. I just downloaded the file you sent and created a tiledBackground here using it.
