Once you have the face you want in the face gen program (read the read me file form the download provided in the original post), go to the "Genetics" tab of facegen and take a snap shot of your screen (CTRL+PrintScreen most of the time - print screen is normally on the same level as the "F" keys and to the right, above delete). This is handy, because you'll have a shrunk version of the head immediately.
Open up Photoshop and select a new document - if it asks for size, make it like 1040 x 700 pixels, just big enough to paste your screen shot into.
Once you have your screen shot opened up in photoshop, select a box around the SMALL head (Not the big head on the left, but where there is space for nine heads on the right, where your head is in the middle) and as much of the neck as you can. Don't worry if you lose some of the neck, but get all the head if possible.
CUT (CTRL+X) this small head out of the screen shot.
Open a new document in photoshop, this time, make the dimensions 90x135 - which matches the dimensions of the template for the fictional player in the download provided by Deft.
Paste your small head into this 90x135 document. You may need to maximize this window and use the "free transform" tool to get the entire head inside the 90x135. Shrink the head a little (horizontally and vertically) too. Select the magic wand tool, then - usually by using the inverse selection tool after selecting magic wand - CUT only the head of your player.
Open one more new 90x135 document and paste the head in here. LEAVE this document with only the head open in your photoshop window.
NOW, open up the fictional player template provided in Deft's download. Once open, on the bottom right, you should see a panel with info such as "red cap" "blue jersey" etc - and room for two icons, a lock and an eye). DESELECT everything down here (it's deselected if there is no eye symbol next to it) apart from the undershirt and jersey - and pin strips, wrinkles etc.
In the fictional player template, you should now have just a jersey with no head, no neck, no background, no nothing but the jersey.
Now use the magic wand to select the upper half (the blank area, don't select the jersey), and CUT (CTRL+X) it - leaving only the jersey.
Now go back to that image of your head, and CUT (CTRL+X) the head.
Go back to your fictional player template with only the jersey, and PASTE (CTRL+V) your head onto the shoulders. Use the free transform tool to get the head centred as best you can on the shoulders, but DON'T worry if there is a gap between the jersey and head/neck.
Add a hat if you want, and a bat, background, change jersey colors whatever you want (do this by reselecting the items that you deselected earlier, on the bottom right). To get the head to fit inside the hat, use the free transform tool one more time.
If you have a gap between the neck/head and the undershirt/jersey don't worry. Zoom in on document until you see the gap clearly, and select either the color of the undershirt (which I do, because it's either black or white) or the color of the jersey, and just color in the gap.
You can blur out the "SI" by, as said by Deft et al, selecting the blur tool (which looks like a tear drop) then selecting the size of the font on the tear drop, and smudging it out.
Save the file as a BMP, find the player number you had in mind in your OOTP game, copy the new file over into the "photos" folder of your league, and Bob's your uncle.
I figured this out after playing around with the free photoshop 30 day trial version (HINT HINT) for an hour or so. Experts may laugh at my method, but I tihnk it's pretty easy if you've never used Photoshop - you just have to locate the tools - which doesn't take long.
Does that make sense?
I hope so.
Attached is a photo I made of the second overall draft pick in this year's (2007) NPBL Rookie Draft - 1B Jason Wallin (he's supposed to look a little rough, like he's had a tough life):
Another one I made - this was my first effort - so the color is a little off on the jersey extension, also hadn't figured out how to stretch the head into the hat with the free transform tool here:
