Is the reason it is a problem at work because you are needing to take the photos at work or because you only have access to the internet at work and therefore worry about filters etc?

If the latter, then not sure what you could do that will get you fired if sending pictures of your breasts or reading this forum while on work time doesn't...

You could make use of the work toilets and send him photos of you in there doing things for him?

If you really want to avoid issues with work internet logs and filters I suggest you buy an internet capable mobile phone... you can use it to take the photos as well. To make things easier, you can also use the mobile phone to access the internet on a laptop (simply plug it in as a modem) without encountering firewalls, blocks or IT departments snooping in your internet logs. The access may cost you a minute rate but there are a number of deals in the UK at the minute that offer uinlimited mobile internet on a phone for a monthly charge so there is no reason to think these are not on offer in the US as well.

You can also, of course, use any mobile phone with a camera to send the photos via text message
