Inserting a .gif image of a blank space is better than using the usual html "nbs" code for a space since that tag is sometimes not properly recognized by certain versions of browsers.

Read tip #10.
Treat the gif just like the image it is. You can even assign it various larger heights and/or widths. Or just use it as a one-pixel space and put in multiple ones if you want a bigger space. It will be invisible on the page. You will have to upload it onto your site just like any other image file. It's handy and simple for those who don't want to learn CSS stuff.
