I have an old page using the old editor experience. It had a few lines where I'd placed small images then a line of text. Hoping to replicate this in a new page using the new editor, but now I find the image scales when the user changes their browser window size, putting it totally out of scale with the text. How do I ensure it retains a fixed size? The scaling doesn't even seem sensible - sometimes when the browser window is small the image suddenly becomes massive, perhaps because of some sort of page reflow thing.
