How do I fix my blogbackground to the right size?

Question

I used the instructions for making my own blog background from http://fillingyourark.blogspot.com/ you can see that only a portion of that is showing. Can someone please help me with this? I can't seem to figure out why it's too big.

Answer 1

Not bad, i presume you worked it out.

I would have tested the site in different screen resolutions, but i am unable to with my current setup. The challenge is to make the layout adapt to the many screen resolutions, not to mention browsers. Which can even be hard to the most experienced web designers.
