Customize the Internet Explorer 6 Toolbar
 

I found this in a few different places around the 'net - hopefully it's helpful:

Customize the Internet Explorer 6 Toolbar

You can choose which features you want on the Internet Explorer 6 toolbar. If you want to simplify the toolbar, you can remove icons, change to smaller icons, or remove the text labels displayed next to the icons.

• Right-click the Standard toolbar, and then click Customize.
• In the Text options list, click No text labels to remove them.
• In the Icon options list, click Small icons to change the default setting.
• In the Current toolbars list, click any icon that you want to remove, and then click Remove.
• To keep your changes safe, right-click the toolbar again, and make sure to select the Lock Toolbars check box.
