In reply to Rob Exile Ward:
Even worse now. I used a photo booth and the photos were rejected because the background came out graded. A local guy with a dedicated camera took perfect pictures for me.
If you're renewing you can now do it online and there's no need for 3rd party signatures. You just need to print off the form.
The whole process, including the rejection of the first photos, took just 2 weeks.
For the sake of a fiver, get the photos done professionally.
