fetch_picture_url $displaytypeinfo group info array

[Pedro!]

I can successfully use the fetch_picture_url() method in combination fetch_pictureinfo() and fetch_albuminfo() methods to get the URL for a picture I have the album ID for but in the scenario that I only have the social group ID what do I do to get the URL?

Extract from the API:

fetch_picture_url (line 388)

Fetches the URL used to display a picture.

* return: Picture URL. Generally relative to the main vB directory.

string fetch_picture_url (array $pictureinfo, array $displaytypeinfo, [boolean $thumb = false])

* array $pictureinfo: Array of picture info
* array $displaytypeinfo: Array of container info (eg, group or album info array)
* boolean $thumb: True if you want the thumbnail URL
