I used the page on the Jackie Collins website where you can specifically request a signed photo (and it's personalised!) on the 14th of June. The address on the letter sent was the 19th of June and I received this morning, the 29th of June. So all in all, it didn't take too long to come from the US!
If anyone wants the exact link, it is: http://jackiecollins.com/autograph-request-form/

I personally am so happy with this and think it is SO nice of a celebrity to offer this via their website free of charge. The fact it comes personalised it really lovely, too.
