I have been requested to create instructions how to Port your character with a custom portrait from PC to iPad, so here it is.
steps to follow:
1) first you must create a custom portrait ,I think if you are reading this you already know how to do this, but just in case you do not here is a link to the forum with instructions how to do so "http://forum.baldursgate.com/discussion/7461/heres-how-to-use-custom-portraits/p1
2) than you must port your saved games to the iPad, follow this link with instructions how to do so "http://forum.baldursgate.com/discussion/11504/transferring-bgee-saves-to-ipad#latest
", if you want to port saved characters in copy and paste the characters folder/directory (the entire folder/directory with the character files inside) to the iPad Library directory (same please where you put the "save" folder/directory)
3) using iFunBox put the portraits you used in the PC version to the iPad in Baldur's Gate -> Library -> Portraits.
EDIT: portraits is spelt with a lower case "p" I have just found In another thread. Sorry, this will fix some issues people are having.
Hope this helps, and don't hesitate to ask if I have made something unclear or if you have any other questions.
Have fun playing Baldur's Gate EE!
