I found a nice solution in pure Markdown with a little CSS 3 hack :-)
![image alt >](/image-right.jpg)
![image alt <](/image-left.jpg)
![image alt ><](/center-image.jpg)
Follow the CSS 3 code float image on the left or right, when the image alt
ends with <
or >
.
img[alt$=">"] {
float: right;
}
img[alt$="<"] {
float: left;
}
img[alt$="><"] {
display: block;
max-width: 100%;
height: auto;
margin: auto;
float: none!important;
}
