I love puzzles! OK... what you see with your background image with wide monitor resolutions is that the image is repeating. The same thing is happening with the original fiblack3d background image but because of the way the image is used (the moon in the middle with dark edges), you can't tell it unless you expand your browser window as wide as you can. You won't notice it until you get to a monitor resolution of about 1400x1050 like mine. Because your image has very defined edges, this trick won't work for you.
There really isn't anyway to stretch your background image without distorting it so what you want to do is make one that is at least 1400px wide or wider. Make sure what you want visable as the main focus is towards the left side of the image and as higher resolutions monitors come along, the image will already fit the table.
I've attached a couple of images to show you that the original theme has this issue but the author out-smarted the browser. You can see the moon start to be repeated.
I'm glad you love puzzles, because I don't:)
Okay - I see what you're getting at, but this is really puzzling to me because the table is defeating all I thought I knew about an image filling the space. What I did, if you go to my gallery again, is to make a new image more in line with the colors I wanted to eventually get that parrot my forum (
http://sunrisers.proboards46.com). I don't know if I have the skills with CSS to get there but I need to try - having someone do it is too expensive. Anyway ...
The new image I made started as 967x120 (like the original). I had already removed the "repeat" snippet from the code. It
still doesn't fill the table, but leaves a blue space like I think another guy said, and it doesn't fill the table top to bottom like the original. Certainly not 120 pixels.
Next step was t increase the width of the new image to 1000x120. Same thing! No top/bottom fill, still leaves a small space at the far right.
Now I'm viewing this on a 20" quality Samsung monitor at 1024x768. Every
other theme displays correctly on that monitor with the same browser. I am left clueless as to why now the top/bottom doesn't fill to 120 pixels, or why the table still stretches when others don't. Did I miss a table tag somewhere in the CSS that determines the width of the table?
And appropos of nothing at all ... the new font I put in the style for the top table doesn't appear:) Gak....
