I am not sure what you want to do. Please explain with more details.

If I have a website open with pictures and add another picture it cancels out the previous picture and then if I click another picture it will just keep cancelling out pictures so I can't keep multiple pictures or movies in my tab bar. I'm obviously having trouble explaining sorry.

If you open a link or image in the same tab then you replace the page that is loaded in that tab and you no longer see the page that was displayed previously. You can click the toolbar Back button to go back in the tab history.

You can open a link in a new tab with a middle-click or via the right-click context menu.
