We present cross sections for the reactions p{bar p}{r_arrow}H{gamma} and pp{r_arrow}H{gamma} arising from the subprocess q{bar q}{r_arrow}H{gamma}. The calculation includes the complete one-loop contribution from all light quarks as well as the tree contributions from the light quarks and c and b quarks. These are the main sources of Higgs-photon associated production at hadron colliders. At Fermilab Tevatron energies, the cross section is typically between 0.1thinspfb and 1.0thinspfb for 80thinspGeV{le}m{sub H}{le}160thinspGeV, while at CERN LHC energies it exceeds about 2.0thinspfb over the same range of m{sub H}. While substantial, these cross sections are not large enough to produce a signal which is discernable above the backgrounds from q{bar q}{r_arrow}b{bar b}{gamma} and gg{r_arrow}b{bar b}{gamma}. {copyright} {ital 1998} {ital The American Physical Society}
