Right after you have made them, i am presuming you are using 'Adobe Photoshop 7/CS', you will need to slice them.
To slice them, goto
www.goodtutorials.com or
www.pixel2life.com and search for slicing.
Slicing will allow you to save the image, as a working website, where you just need to edit a few bits here and there. You will end up with a images folder and a XXXXXXX.htm file.
Then you need a program such as notepad, frontpage, dreamweaver, and then you can alter your XXXXXXX.htm to how you require.
Hope that helps - Any problems give me or someone a shout,
Perry
