Sita, glad you liked them! That was kinda the point!
Liss, the trick to editing these things, if you just want to change the color:
1. Select the layer in the layers palette.
2. If you don't see the list of layer effects for that layer, click the little triange to expand it.
3. Double-click one of the layer effects to open its editing window. You're probably most interested in the Color Overlay effect.
(Or: Just select the layer and pull down under Layers to Layer Style. If you're using a version of Photoshop older than Photoshop CE, this is labeled Layer Effects.)
4. To change the color, click on the little color swatch in the Color Overlay editing window.
5. Play with the different modes for applying the color overlay.. I usually use "Multiply" mode. Note that you can also adjust the intensity of the color fill from 1% to 100%.
That's all there is to it. Just play with the color fill in the sundry layers to get what you want. THEN:
a. Control-A to select all.
b. Control-SHIFT-C to "copy merged." This copies the merged result of all your layers to the paste buffer.
c. Go to your .bmp window and paste.
d. Pull down under Layers to Flatten Image.
e. Save the .bmp file.
f. Refresh the view in Body Shop to make sure you got what you want.
g. If that's not what you want, edit some more, then repeat steps a through f until it's just right.
h. Enter a description in the little text box in Body Shop.
i. While you're here, it's a good time to do a screen capture so you'll have a preview image to show on the web.
j. Import into the game.
k. Go to your SavedSims folder, View Details, Click sort by date twice and the latest file sorts to the the top.
l. Copy that file to some other folder. (I have a folder named "Export" in my The Sims 2 folder for this.)
m. Edit the filename to get rid of the extraneous characters and put the initials for your site at the beginning of the filename.
If you do that it will be easier to find your stuff in their downloads folder and also makes it much easier on them because your stuff won't sort in among all th extraneous files that the game generates.
n. Drag it onto that WinZip icon on your desktop and zip it up.
o. Open your site in NetDrive (or somesuch) and copy the .zip file to your /dl folder.
Ta da! It's time to tell the world about it!
