Yes, I use css, not the HTML. The HTML img tag has the css class. Some examples:

.pic_half {
  padding-top: 3pt;
  height: auto;
  width: 50%
}

.pic_small {
  padding-left: 3pt;
  padding-right: 3pt;
  padding-top: 3pt;
  height: 80px;
  width: auto
}

.pic_wide {
  padding-top: 3pt;
  height: auto;
  width: 75%
}

Several pic_small can be on same line, hence L & R padding.
pic_half and pic_wide are intended for single images per paragraph.
I don't put text in the same paragraph.
