picturebox do not updated when clicked in datagrid

Question

I try to build a database explorer to view pictures in the database(ms access) with a search function. It been working well with i can click the data in the datagrid and picturebox showing the picture of the data. However, when i try to do a searching, let say when i typing 'ANIMAL' in the textbox, the result show in the datagrid but the picturebox did not updated to the 'ANIMAL' picture. And when i delete the searched text in textbox, the picturebox also did not respond when i clicked the data. I know i cant explain well due to my bad english, so i attach the project in here. If any of expert here know how to fix it or recommend me another ways to do the project,i highly appreciated. have a nice day , thank you :)
