Describe the bug
As a visitor, when I go to the homepage it gets downloaded the full image size of the avatars on Last Activity
To Reproduce
Steps to reproduce the behavior:
- Go to homepage (ie meta.decidim.org)
- Scroll down to "Last activity" block
- Inspect the image and see that's using the full image
Expected behavior
To see the thumbnail. As it is now it's a problem on performance (doesn't scale well, mobile visitors can have issues with their mobile data plans, etc).
