feat: added arrows to scroll between images

[QyuBee]

Add navigation arrows for image carousel

Description

In order to enhance user experience when navigating between images of a monument, I have added two arrow icons for easier navigation. These icons are linked to the prevImage() and nextImage() functions. Previously, these functions were only accessible via the keyboard's "left arrow" and "right arrow" keys, which might not have been intuitive for new visitors.

Changes

• Added two arrow icons for navigation between images.
• Linked the arrow icons to the existing prevImage() and nextImage() functions.
• Implemented a new activate_scroll parameter in the openImage function, allowing the arrows to only appear if there are multiple images available. This ensures that the navigation arrows are only displayed when useful.

Screenshot

Here is a screenshot of the added arrow icons:

Impact

• More intuitive navigation for users, especially for those unfamiliar with keyboard shortcuts.
• The arrows will only be visible when there are multiple images, avoiding unnecessary clutter.

I hope this feature proves helpful in improving the user experience.

Hey @QyuBee that's great! For the record, Monumental is in a deprecated state due to being unable to find a maintainer. It seems you're comfortable enough with the code to modify it, and have been able to get it building, which is more than I can say for myself. If you're interested in continuing to use it, I'll just be forward and ask: would you be interested in taking over maintainership? I'm happy to help with deployment. For clarity, even if I merge this, I don't have an environment where I can build it in order to deploy it.
