Never actually tried it with images. It might take several callLaters depending on when the image arrives. I usually test this out by adding a button that prints out the textWidth/Height after I can see the final appearance. If it works then, then I know it is a matter of figuring out how long to wait. Otherwise, some other solution is needed.

Alex, I appreciate the guidance! I've tried using callLater and it does seem to help for text-only values of htmltext in a textarea. However, it still seems to ignore the size of any images regardless of when I validate and check the textHeight value... Do you know of an example I can refer to?
