Fix: Correct hidden attribute for swap image

[MarsonKotovi4]

What was done:

• Fixed an issue with the use of the hidden attribute on the <img> element. Now, the display: none style is used to properly hide the image.

Why this is important:

• The hidden attribute doesn't always work as expected and can cause display issues in various browsers.
• Replacing it with display: none ensures more stable and predictable behavior of the element.

Testing:

• Verified that the image correctly hides and shows based on the condition.
• Ensured that there were no side effects on the layout.
