Beautiful but background comes through photos

I really like the NatureFox theme, except for a couple of things.

1) When there are photos in the posts, the background image bleeds through. There doesn’t seem to be a setting for opacity in the media dialogue, so other than some code hacking, which is a little beyond my abilities, I don’t know how to fix it.

See this page for a quick look. It’s weird, and even awkward, especially on skin:

2) The text is a litte too pale and just a little too small by default. I’m in my mid-40s so things like that, well, you start to notice.

Many of my customers are around my age, so this sort of thing becomes more important in the look and feel of one’s web page.

Again, I really like the feeling of the theme over all, so if those things can be adjusted, it would be ideal. It is very difficult to find an off-the-shelf theme that is good for the metaphysical business. I’d like to stay with this one.

FIVE STARS if those things are fixed.

Thanks!
