We determine the constraints on the anomalous top-quark coupling associated with the flavor-changing neutral current vertex {bar t}c{gamma} from the limits on the b-quark rare decay b{r_arrow}s{gamma} and nonstandard top-quark decays. Based on these constraints, we discuss the experimental observability of the rare decay mode t{r_arrow}c{gamma}, both at the Fermilab Tevatron with a luminosity upgrade and at the CERN LHC. {copyright} {ital 1997} {ital The American Physical Society}
