I need help with something. On my wiki, I want to change the way that gallleries are automatically set up. You know how wikia has a pre set border size, photo size, photo spacing, etc? I want to change that so that galleries are automatically preset to this: Can someone help me with some type of CSS that will make galleries automatically like this? Thank you! I really appreciate the help! :) 
 * The photo size should be 170px, the photo orientation should be set to square and the photo spacing medium.
 * The gallery positioning should be to the left.
 * The caption size should be medium, the alignment to the left, the caption below the photo, and the caption color black.
 * The border width should be medium and the border color should be purple.
