p.center {
text-align: center;
}

Use the above style within HTML images like this:

<p class='center'>
    <img alt="img01" src="../Images/Title_Image.jpg">
</p>

The second way to quickly center each of your epub images in Sigil would be to click and highlight each image in the Sigil html editor in turn and then just click the 'Align Text Center' button in the Sigil Toolbar.

You left out the indent. I had to remove the p as I cannot stand p. CSS styles. You need the indent to be 0 because p should be the default for most paragraphs and that includes the indent.

p {
  margin-top: 0;
  margin-bottom: 0;
  text-indent: 1.2em;
}
.center  {
  text-align: center;
  text-indent: 0;
}
