I have a problem in using a plugin, Simple PHP Gallery, for WordPress.
The picture plugin can display the photo uploaded to the website.
However, there is a layout problem. The sidebar of my web blog does
not fix in the usual position but fall below the picture thumbnail. My
website is http://www.379sky.com/wp and please give me advice about
that. The only problem is that when it displayed
http://www.379sky.com/wp/sp-gallery/folder/gallery , the layout
problem occurs. The plugin is ok when viewing photos one by one.
I'm in urgent need for help. Please answer me back as soon as possible. Thanks!

Yep I'm getting different results on different browsers. Do you want
the images in two columns or one?

Without having access to the php and knowing what setup you have I
will assume you can modify the styles. After:

<style type="text/css" media="screen">

/* BEGIN IMAGE CSS */

put:

	#content {width:300px;display:inline;float:left;}
	#spg	{width:300px;display:inline;float:left;}
	#gallery {width:300px;display:inline;float:left;}
