We investigate the possibility of studying the strange hidden-charmpentaquark state $P_{cs}(4459)$ by photon-induced reactions on a proton targetin an effective Lagrangian approach. The production process is described by the$t$-channel $K^{-}$ exchange, the $u$-channel $\Lambda$ exchange, the contractterm, and the $s$- channel nucleon pole. Our theoretical approach is based onthe assumption that $P_{cs}(4459)$ with $J^{P}=1/2^{-}$ or $J^{P}=3/2^{-}$ canbe interpreted as a molecule composed of $\bar{D}^{*}\Xi_c$. Using the couplingconstants of the $P^{J^P}_{cs}$ to $\gamma{}\Lambda$ and $K^{-}p$ channelsobtained from molecule picture of the $P^{J^{P}}_{cs}(4459)$, the totalcross-sections of the process $\gamma{}p\to{}P^{J^P}_{cs}K^{+}$ is evaluated.Our calculation indicates that the cross-section for$\gamma{}p\to{}P^{1/2^{-}}_{cs}K^{+}$ and $\gamma{}p\to{}P^{3/2^{-}}_{cs}K^{+}$are of the order of 10.0 pb and 5.0 pb, respectively. In addition, we computethe cross-section by assuming $P_{cs}(4459)$ as a compact pentaquark and findit is quite different from the results of $\bar{D}^{*}\Xi_c$ molecule.  Those results can be measured in future experiments, such as the Electron-IonCollider in China and the United States. And can be used to test the nature ofthe $P_{cs}$.
