Theme change since upgrading to 1.5.7 from 1.5.1

*** Just an update of my original post below, I removed the references to the images from the content.php & added in an &nbsp for a slight indent, now I need to shrink the left column to get back to what I had - hope this helps anyone out there trying the same.

Hi, this is just a specific question with regard to a change that's been made to the default theme between 1.5.1 & 1.5.7. I've happily been running Gallery 1 since 2004 or so. Most customizations I'm okay with, this one I figured I'd check here first.

In the view on my site:

There is a now a "visible" tree view on my sub-album listings, and it's affecting my layout, causing word-wrapping that didn't occur before.

Does anyone have any suggestions for this? Can I remove that capability so it looks like my prior version?

I am going to play around with it now, just looking for comments on the best way to do it. Looks like it's using gifs like: joinbottom-right.gif.

Thanks!

Mike
