Gallery wall options?

Hi,

I am new to Rise and need to share a gallery of about 50 images, with a short caption underneath. I see that I can do this using the grid of images options, but my concern is that it will take many rows of 4, which can look a bit monotonous on a Rise page. Is there another option for me to share this information? Something that is not too labor intensive and doesn't require expert knowledge because I am still learning the how to use the platform?

Thanks!

Steph
