You mean, how do you export her as a morph target or character, OR how do you host it on the internet? If it's the first, the quick solution is to follow the instructions on page 58 of the Poser manual for exporting to .OBJ format, remembering that there's an additional step (a dialog box with several checkbox options). Unselect everything in the hierarchy by unchecking Universe, then check only Head. When the dialog with the six or so options appears make sure all options EXCEPT 'weld' are checked. The resulting .OBJ file is your morph target. To keep from illegally distributing the complete mesh for the head, a practice known as 'squishing' is necessary; open the .OBJ in a text editor and delete all lines not starting with 'v[space]', such as 'vn', 'vt', 'f', etc. These extraneous lines aren't needed by Poser when importing them as a morph target because the data in them is already in memory. Also, a squished morph is considerably smaller than the unsquished form.
