Here is the pics

I would like them better without glass. However, if these are important prints (sentimental or otherwise), glass is important for preservation.

What style is your home? The frames and the marbled mats are very traditional. If you want a new fresh look, I'd consider new frames and mats.

I asked ChatGPT mock up a new mat and frame. I personally might have picked a slightly darker frame but I like how it turned out.

There are non-reflective glass choices. Take the pieces to a frame shop.

As far as reframing, only if you have a specific room style where the current ones conflict. To me, frames coordinate with the picture.

My style is Modern Cottage

The pic with new frame is also too light for me, my walls are light. Looking too hang them on stairwell wall of my foyer/entryway
