OK... this "save and test" process will only work if you've put your new props in the same folder on your computer as your "old" props....
First, save your work. Using the NotePad menu, click "File" and "Save As". Be sure to save the new version of the code in the same folder on your computer as the props, otherwise, your test won't work properly.
When you do this, NotePad will tell you that a file with that name already exists, and will ask if it's OK to replace it. The answer is "Yes". Click the "yes". But... wait! Don't close down NotePad, just leave it open, because we're going to add more props.
OK... now, crank up your browser (internet explorer). In your browser menu, click "File" then "Open".
When the file open window appears, click the "Browse" button and browse to your doubleclickdollmaker.html file that you just saved.
Once you've got the file name in the "open" window, click "OK".
Your dolllmaker should open, with the usual little alert box asking you to read the instructions. Just click the OK on the little alert window like you usually do.
Go ahead, be brave - double-click your newly added background. It will pop up to the Creation Zone.
Now, double-click a pair of wings... they will also pop up to the Creation Zone.

Well, look at that! It worked! You're a genius!
Hey... wait a second... does that look a little awkward? That big background right next to the wings, sort of pushing them out of the way?
No problem. Let's add a "break" to move the wings down to start a new line.
Back to NotePad... But!!! Don't close your browser yet... just leave it where it is, we'll use it again...
Add a code tag of <br> between the background and the wings, like this:

Save the file like we did before, pop back over to your browser, and click the "refresh" button (or just press F5 on your keyboard).

There we go. That looks better.
OK, now what? Tops, you say? You've got tops to add? No problem. You can handle it.
In NotePad once again, click "Search" and "Find" and type in "top". Click the "Find Next" button.
Bam!
No, no, wait... something is wrong..... this says "grayskirtop.gif"... and it's in the "dresses" section. We wants to go to the tops section. What's up with dat?
Don't panic.... Just click the "Find Next" button again...
Bam! Ah.. that's better... here we go... "bluediamondtop.gif"... now we are in the tops, and you can add your new top using the same process that we did before. Just copy / paste the "bluediamondtop.gif" line, modify it, save... test...
Woohoo! Look at you go! You're adding new props like a pro. And you didn't need no steenkin' helper application either. Nahnahana! Easy Designer can kiss your booty!
New props all added? Wonderful...
Now all you have to do is upload your newly modified code to your web site, just like you did the first time.
Don't forget to check it out to be sure everything still works.
Oops... Uh oh.... you uploaded your new code, and one of those stupid annoying little red Xs showed up where a new prop should be?
Don't panic, check... are you sure you uploaded that prop? Oops... forgot that one, huh? *grin* No problem, upload it, and life will be good.
Have fun.
Blessings
