I hear what your saying but remember Photopost Pro is not a vbulletin addon or plugin it is a full featured gallery that may integrate with a list of forums we note. vbGallery is an addon which is made for vbulletin and works like the other apps your talking about.
The only way to put pro stuff into
vb is plugins and currently these are all mods or hacks as it is called not part of the product because that is not how Pro is designed. Pro can use the
vb header footer style login but it is not part of
vb.
vb does not even know Pro exists.
Like I said it would be possible to add some kind of check for a specific
vb pro plugin and change profile links but it is a matter of what is core product and what is considered a hack/mod.
