Gallery pictures change sizes... this is not solved. help

OK so I added the gallery bloc and i want to add 6 pictures. Now the pictures are in different sizes because some of them are posters, some of them logos, some of them landscape ads…etc…
I don’t want the pictures to FIT in the 221x221 square placeholders because they will be distorted. What I need is that the pictures just go inside of those placeholders keeping the 221x221 placeholder size, so when i click on the placeholder the lightbox feature will open the full picture size…
The placeholder can show part of the image inside… in MUSE was super easy, can be done in Blocs too?

OK I founded a way…try this, try that, …
if any of the experts here knows a simple way let me know please…

OK no… I was wrong… I thought touching the padding, adding the image in custom class manager and all that will fix it but no. If I do that you still can see like a shadow of the padding…weird…
any thoughts?
