If you can live with .jpg, .gif, .png, etc. images, then the advice of Doitsu is perfect. But if you want to use svg images, then you don't need to use Inkscape as I said before; things are still easier You only need to write svg images in Sigil (all images will be the same, only will change in the letter you will use there). I give you an example:

SVG for letter A:

<svg 
   xmlns:dc="http://purl.org/dc/elements/1.1/"
   xmlns:cc="http://creativecommons.org/ns#"
   xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
   xmlns:svg="http://www.w3.org/2000/svg"
   xmlns="http://www.w3.org/2000/svg"
   version="1.1"
   width="100"
   height="100">
  <text x="50" y="100" text-anchor="middle" fill="black" style="font-size: 100px; font-weight: bold">A</text>
</svg>

Using the svg in the ebook:

<p><img class="DropImage" alt="Image1" src="../Images/Image1.svg" /> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla ac tellus nunc....</p>

And the stylesheet is:

p {
    text-align: justify;
}

.DropImage {
    float: left;
    margin: -12px 5px 0 0;
}

Here is like is looks in Sigil:



Here is as looks in ADE:



Below you can see the respective ePub. Of course, you can change the size, the color, etc. for each drop cap (you can use all the posibilities of the svg text).
