I would expect that the costs are added to your mobile telephone bill and the charges would depend on the size of your photos. For example, T-Mobile charges 0.75p per kilobyte of data sent/downloaded. Some images on my mobile telephone can be up to 200kb at a time, so it would cost me �1.50 to send each image. I would recommend that if this is something you plan to do regularly, you consider switching to one of T-Mobile Flex-T packages and then paying an extra �7.50 per month for unlimited data transfer in order to avoid ludicrious charges next time.
