Hi ahmad, quite disturbing indeed😅 But the little crawlings have their place in the ecosystem. I got my first trauma when I found a tick in my thigh.
Now, if you want to contribute these to the library, there's actually a template that you can follow, since the process it's done automatically if done correctly:
This is an example: https://hiveblocks.com/hive-174695/@redheadpei/lil-images-for-let-s

Use appropriate keywords for your pictures: check this post for more details: @quantumg/lmac-image-library-statistics-what-is-much-or-what-is-rare
There's also a list of most demanded pictures, so if you have some stored would be a great help

When you're done you can check if everything's alright here:
