I worked as a business development guy on a major contracts team. So my usual role was finding £100k+ contracts and negotiating the tender process. I'd regularly get bonuses when the deal was closed. However I really was a coder. I proposed a CD that we'd send to architects to showcase our work. It was a simple HTML interface that would pop up when they put the disc in. I did all of the coding, graphic design and packaging. Then mailed it to prospects and made it available to my team. I did this without pre-negotiating any kind of extra payment even though it 'wasn't my job'. I just knew it would be incredibly useful to have a high-res portfolio. I was very pleased when a Director gave me a £4.5k bonus for the work. Note that I completed all of the work on my salaried time. Too many people box themselves into a 'not my job' mentality. I don't think a bonus should be expected by the OP as it was just doing his job. No harm in asking though!
