We calculate the radiative decay widths, two-photon ({gamma}{gamma}) and one-photon-one-vector meson (V{gamma}), of the dynamically generated resonances from vector-meson-vector-meson interaction in a unitary approach based on the hidden-gauge Lagrangians. In the present paper we consider the following dynamically generated resonances: f{sub 0}(1370), f{sub 0}(1710), f{sub 2}(1270), f{sub 2}{sup '}(1525), K{sub 2}*(1430), two strangeness=0 and isospin=1 states, and two strangeness=1 and isospin=1/2 states. For the f{sub 0}(1370) and f{sub 2}(1270) we reproduce the previous results for the two-photon decay widths and further calculate their one-photon-one-vector decay widths. For the f{sub 0}(1710) and f{sub 2}{sup '}(1525) the calculated two-photon decay widths are found to be consistent with data. The {rho}{sup 0{gamma}}, {omega}{gamma} and {phi}{gamma} decay widths of the f{sub 0}(1370), f{sub 2}(1270), f{sub 0}(1710), f{sub 2}{sup '}(1525) are compared with the results predicted by other approaches. The K*{sup +{gamma}} and K*{sup 0{gamma}} decay rates of the K{sub 2}*(1430) are also calculated and compared with the results obtained in the framework of the covariant oscillator quark model. The results for the two states with strangeness=0, isospin=1 and two states with strangeness=1, isospin=1/2 are predictions that need to be tested by future experiments.
