I upload 'em to my Photobucket account online, and then post the image link/code. You'll be able to tell the right type of link by the "" at the beginning, followed by "http://www.blahblahblah..."
Glad that Photoshop tutorial gave you some info you could use with your program. You did a nice job with it. It's almost the same color as the '62 Dodge Lancer my folks got from my uncle as a wedding present.
You should be able to change the color of your interior (or anything else) by using what they call the Lasso tool in Photoshop. Look for it toward the top of the toolbar with all of the icons on it. It will allow you to outline the desired area and then use the tools (Image/Adjustments/... in Photoshop) to darken/lighten/change the color.
