Hello daveball, first of all let me correct your website link: it's http://www.irishwebcreations.com/ (you forgot the .com).

To correct your source you just need to refer it to the relative place on your computer or server.

For example. Lets say your website is stored inside a directory called website.
In that directory you have the index.html file. If you put your menu there you would refer it by it's name, i.e. your image name is menu.gif you would refer to it as menu.gif.

If you have a subfolder named menu (i.e. you have the website folder, inside of which you have the index.html, then you have the subfolder called menu in which you have the menu.gif file).

In that case you'll refer (from the index.html) that menu.gif file the following way: src="menu/menu.gif"

Everything is relevant to your main html (index.html), so if you have the files put at the same directory the index.html is, you simply type the name of the file. If your file is stored in your subfolder you put the name of the folder i.e. subfolder/filename.filetype

Hope that helps.
