It appears that any image added to an article will be configured so that when the user hovers their mouse over the image, the cursor becomes a magnifying glass and they can click to zoom in on it. This is fine most of the time, but I wish I could disable this for certain images. For example, I have an article with tabs, and I want to include a little icon in the tab label. I edited the HTML for the tab and added an img tag, and it displays it, but when I hover over the icon in the reader interface, I get the zoom option. If a reader were to click on this icon, then instead of selecting the tab, it would just zoom the icon.

There could be other cases where I don't want the zoom option for an image: e.g. if I use an image in a button or a link, or whenever the image is a little icon/decoration, and there's just isn't a need for the user to zoom it.
