In this paper, we investigate the shadow and thin accretion disk around Ay\'{o}n-Beato-Garc\'{i}a (ABG) black hole (BH) coupled with a cloud of strings (CS), characterized by the nonlinear electrodynamics (NLED) parameter g, and the CS parameter a. By comparing shadow diameters with Event Horizon Telescope (EHT) observations of M87∗ and Sgr A∗, we have established constraints on the BH parameters g and a. Additionally, we analyze the BH shadow, lensing ring, and photon ring features for the ABG BH coupled with CS. Our results indicate that the shadow radius increases monotonically with the CS parameter a, while it decreases with increasing g. Finally, the study explores the physical properties and observational signatures of thin accretion disks around ABG BH with CS. The results show that an increase in parameter g leads to a hotter and more luminous disk, while an increase in parameter a results in a cooler and less luminous disk.
