We present 450, 850 mu m and 1300 mu m images of regions with embedded candidate protostars. Some of them are associated with HH objects (HH 7-11, HH 1-2, HH 147, HH 111, HH 108) and have been previously identified in the course of a 1300 mu m survey. Other regions were taken from the IRAS PSC (04239+2436, 04368+2557, 20050+2720, 20386+6751, 22134+5834, 23011+6126). The new mm/submm images show the detailed structure of the regions some of which contain new compact sources as well as extended emission features. The inferred mm/submm fluxes are combined with IRAS data in order to derive the temperature of the associated dust, its mass and the re-radiated luminosity. Taking the ratio of FIR-to-submm luminosity as an indicator for the evolutionary stage, we find that 15 out of 17 sources have L_FIR/L_smm < 200, indicating that most objects are probably genuine protostars. For the first time, we detect dust emission associated with HH objects themselves, H_2 and CO flows which we interpret as density enhancements swept up by the ejected material.
