Can we control which responsive images get generated via Media Library?

Hi everyone,

I was wondering where do I see these multiple file sizes? I only have access to a single url from media library. Where are the others? Do they just have small_ medium_ and large_ prepended in front of the original filename? Also, why is Strapi generating random characters after the filenames even if I don’t already have a file with the same filename? As an example, when I upload strapitest.jpg I get /uploads/strapitest_52de418f82.jpg. Thank you for your help.
