Unfortunately the problem is more subtle than that. The images are correctly centered in the EPUB and the DOCX translation, but not in the PDF. The CSS is correctly configured to center the images. Here is an example:

Here is how the images are included in the EPUB:

<div class="illustype_image_text"><div class="image_text" style="width:65%"><img src="images/e9780486153353_i0004.jpg" alt="e9780486153353_i0004.jpg"/></div>

And here is the definition of "illustype_image_text" in the CSS:

.illustype_image, .illustype_image_net, .illustype_image_tab, .illustype_image_text, .illustype_image_text_net, .illustype_image_math, .illustype_image_deco, .illustype_image_deco_net, .image_orig_tab, .illustype_image_externe, .image_sep_para {
		text-align: center;
		margin-top: 1.5em;
		margin-bottom: 1.5em;
		page-break-inside: avoid;
	}
