TextMesh Pro How to Set a Sprite's Size

I need to add some inline images to a rich text field. I followed the very detailed instructions, created the atlas and added the tags, and the images show up in the field (referencing by sprite name didn't work, but by number does). But I can't find any way to set the size of the images. Line height doesn't work. Changing the font size changes the image size, but causes all kinds of alignment problems - the image is off the edge of the field and the image overlaps the following text.

Is there a simpler way to insert an image and set its size without having to adjust everything else? I have a simple HTML document that has paragraphs of text with images in between the paragraphs that I need to reproduce. Unity rich text docs list a <quad> tag for images, but I don't see that tag listed for TMPro. Is there a better way to do this with TMPro rich text or are (large) inline images not supported?

 

Thanks. Setting the sprite size works like setting the font size, the image is shifted and overlaps text. Looks like rich text doesn't work like HTML when it comes to inserting images. I think it will be easier to just divide the text up into blocks and insert images between the blocks. It's in a scroll rect, so setting up a layout group should be quick and easy, relative speaking.

 

Adjusting the offset moves the image around, but the Adv setting does nothing that I can see. But that's OK, I can add spaces in the text to allow for the images. So this will work. Thanks.

Attached is an example of the web pages I'm trying to reproduce, just paragraphs of text with images in between.
