Many other posters have said 6 months, but it will likely be much earlier to get the first images. 6 Months is the time frame for regular science operations. It is likely NASA will share some images well before that from the calibration phase as part of mission PR. As regular joe's on the internet we are only interested in those PR images, regular science operations are more important for astronomers applying for time on the telescope. Beyond those initial PR images, we can perhaps expect some PR worthy research papers (i.e. kind of papers that will get posted here) maybe a year from now, given the first projects will get access 6 months from now.
