What's Wrong?

When the user goes to click the "X" button on an image preview, the "X" button with the red background to close the window pops up over the image preview button, causing the user to accidentally close the window, instead of the image preview.

<img width="735" height="450" alt="Image" src="https://github.com/user-attachments/assets/2df9dbc5-0062-42aa-9527-44bc61a49535" />

What Should Happen?

A) The user should be able to click anywhere around the image to close the preview, as is standard behavior.
B) The close button should not be in the top corner, or it should not get covered by the button to close the window
