Thank you for your post.
Assign an object name to each tab selection. You can then specify in a script to "Go to Object [ name ]". Therefore, if you need to add information to the Gold Moulded tab, assign the object value "Gold Moulded". Then, you can use Go to Object [ "Gold Moulded" ] script step followed by the Insert Picture... step. You will then remain in the Gold Moulded tab.
Let me know if you need clarification for the above steps.
