It really is good practice to make your site pleasant for anyone coming to view your site.
I'm trying really hard, but as I've said earlier, I'm new to html and wordpress :) The good thing is I read alot and I learn fast, and that there are people like you who help us beginners.
I'm using WinXp with SP2, but I don't think this has anything to do with it, or at least it shouldn't.
And yes, I have created a kind of "netowrk" between my 7 blogs, and on each of them I have installed different plugins to try them out. This seems to be a specific problem related to NextGen, or something in NextGen. The picture section is the only one with the big space in IE6.
I had exactly the same problem on another section where not a single plugin was installed, but instead I had some scripts for live time and weather forecast. I've added them in the left column, and they've created the same issue as NGG, and only in IE6. After I took them out and put them in separate pages, the problem was gone.
* It might have something to do with the fact that my html code is not that great, I have like 134 errors in my theme, which I compiled using tutorials and advices. :) I'm trying to get them out using Firebug and Web Developer for Firefox, but it's kinda' hard for me... Maybe if you take a look at the code you'll be able to find something there, 'cause this is impossible for me in my current stage.
