If you're trying to send this preset to her so that she can use it on her own character, what you'll need to do is send her the entire contents of the preset folder in which you made it in. So for example, if you made the preset in preset 2, you'll have to send her all the preset 2 textures and material files. She has to place this in her own preset_2 folder for this to work. She then will have to type her username exactly how it appears (Capital letters count!) into the username space on the game login screen. Then she'll have to go to the preset maker through the Creative Den. She'll pick preset 2, and then hit export. She'll then have to login to the game and edit her character, go to the last tab, and hit "Use Preset" For others to see her preset in game, she will need to put up the .fhp (with her correct username) download link for others to download.
If for some reason this is unsuccessful, open your material file in notepad and check what is listed next to the word "texture". If the name of the image in the material file does not correctly match the name of the texture files you have, then you have to change the name in the material folder to match the images in your folder. File format counts as well, so if your image is a .png, make sure it reads ".png" in your material file.
For example:
Material file reads: "texture preset_2head.png"
Then Image must be named as "preset_2head.png"
Also make sure that she is replacing the material file existing in her preset folder with the one that you are giving her.
