I think you need iLife '08 and create a web gallery on .mac using iPhoto '08. You should then be able to upload photos to your .mac account from your iPhone.
i do have ilife 08 i just bought a brand new iMac...and i did it through iphoto, for some reason it wont let me upload from my iphone and its starting to bug =/
In iPhoto '08 you need to change the settings of the albums/events, which have been published to the .mac web gallery, to enable "Allow photo uploading by email".
