GTMetrix Recommendations - Page Speed-YSlow - Scaling of Images & ETags

I have been trying to improve my page speed and one of the recommendations is the following.

https://www.riskoracle.com/media/com_easysocial/avatars/text/user/52c5706bc98f911ffbc794f5ffab068d.png is resized in HTML or CSS from 180x180 to 32x32. Serving a scaled image could save 1.2KiB (96% reduction).

https://www.riskoracle.com/media/com_easysocial/avatars/text/user/5b79c40fa7c2bd12dd2df53c4a2b6836.png is resized in HTML or CSS from 200x200 to 32x32. Serving a scaled image could save 211B (97% reduction).

I would also think that the correct scaling of avatars would be standard in a release?

On my YSlow result I also have:

Some are not Stack related but how can I do this in Easy Social?

Thanks a lot.
