Maybe it would be better to have a placeholder for the image and specfic the 
image as a separate element or at the end of <desc> element.

For example
<item>
    <desc> this is a picture %0. Do you like it?</desc>
    <img src="..." />
</item>

This way the string is easily replacable for example in translations.
In the code you just take the text and substitute the image tag with 
QString::arg

QString text = desc.arg(imagetag);

Cheers,
Kevin
