¿SOLVED? Background image on header on low quality

[Anarcoma]

Hello!!!

I'm trying to upload a .jpg image to the header (on Bender Theme) as background. But the image its uploaded with a very low resolution (pixelated / blur)...

Here is my .css on the theme/css folder (main.css)

#header
{
background-color:#ffff99;
background: url(../images/thefile.jpg) repeat;
width:100%;
height:auto;
display:block;
position:relative;
margin-bottom:15px;
padding-bottom:25px;
}

When i open the image with a navigator on explorer, firefox etc
(http://www.misiteexample.com/oc-content/themes/bender/images/thefile.jpg) is still pixelated... i mean, i think its not a problem with the .css...

Thanks a lot!

Solved (just a while)...

I had saved the .jpg as a .png file... (and change the .css too, of course)

I think it's a temporally solution, but not THE solution...
