Bad idea.

This has been discussed quite a few times over the years. Here's some of the more recent threads:

• 2019: "create a useable TOC when book uses images for chapter headings"
• My 2019 comment on /r/selfpublishing: "Any tips on adding ornamental art in Sigil or Scrivener?"

And why are images-of-text bad?

In the 2018 post I link to in that 2nd response:

  • Color, font, font size, [...]

There are a few ways to do this:

- - -

Method 1. Like DNSB said, using title="" is how you manually override what appears in Sigil's TOC generator:

<h1 title="1. The Beginning">Chapter 1: The Beginning</h1>

Would appear as:

• 1. The Beginning
  
  • In the TOC + after Tools > Table of Contents > Generate Table of Contents.
• Chapter 1: The Beginning
  
  • In the text itself.

Method 2 (Strongly recommend against). There are ways to "hide" an <h1> using CSS's display: none:

HTML:

<div class="chaptertitle">[[[Your image code here]]]</div>

<h1 class="invisible">Chapter 1: The Beginning</h1>

CSS:

 h1.invisible {
	display: none;
}

but this has the potential to break in many readers.

Method 3. Like KevinH said, embed+subset a "fancy font" and use it only for your chapter titles:

HTML:

<h1 class="fancytitle">Chapter 1: The Beginning</h1>

CSS:

h1.fancytitle {
	font-family: "Lucida Handwriting", cursive, sans-serif;
}

For info on how to do that, see my mini-tutorial I wrote for embedding Japanese fonts. (Instead of <span class="japanese">, you'll be using <h1 class="fancytitle">. You can then follow Steps 4+.)

For more info on "embedded font" issues (licensing, "Publisher Fonts" setting, etc.), see discussion in this recent thread: "ePub chinese fonts".

All methods (and pros/cons) were discussed in detail in those linked threads.

I completely recommend against using "chapter heading as images" though.
