One problem we've come across repeatedly is how to get an inline image to sit between two paragraphs with an even space above and below it. You can always try doing this by eye, but we feel that it's best to use a technique that allows you to get it exactly right every time.
The main issue you have to contend with when trying to do this is a combination of the leading and the pinning of the anchored object.
Taking a look at the default setting for the image with the text jump, you can see that it's not centred between the lines of text. We use the following method to deal with this:
So when we do this…
We now have an image that is spaced evenly between the two lines of text.
If you want this method to work with the baseline grid, you’ll need to make sure that the space above is a whole number of lines, plus half a line. The space below should be the same, plus the X-height.
If you’re working with images with captions, the easiest way is to use the object style you’ve created for a box, inside which your grouped images and captions can sit. (All you need to do is paste the image and caption into the box and then shrink the surrounding box to fit its contents.)
