By default, Markdown doesn’t support aligning images. You can, however, use CSS snippets to style them. Something like this should work. Add this as a CSS snippet and enable it. Tested with the default theme.
img[alt*="right"] {
float:right;
clear:right;
margin-left: 1rem;
margin-bottom: 2px;
margin-top: 2px;
}
In your note, you would add |right to the image link like this:
![[Myaku-Myaku.png|right]]
