We have a Confluence page that shows all our employees with pictures. It's a table that is sorted by last name and with rows per Picture and info (name, start date, office)
We have about 250 employees and therefore high res pictures on the page.

In Confluence Server the page wasn't the fastest to load but it was bearable. Now in Cloud, load times are horrific and we already had to downsize (reduce resolution) for all pictures. As well as load times, we have issues with sizing and resolutions as well.
I've already tried out multiple other designs and even 3rd party Apps.
Does anyone have a better solution?
