Issues with image header caption in articles

[nicolewaldrip]

When creating an article and using the "Advanced Style Option" to add a header image, if you choose to also add "Header Image Optional Text" I would expect it to show directly below the image, not below the date and byline.

Is it possible to move the "Header Image Optional Text" to directly below the image? If so, can we also change the label for this to be "Image Caption (Optional)"? As this is a more common way to phrase what that content is meant to do.

Additionally, it looks like it cuts the text off after a certain number of characters, can we extend this? If not, we need to identify in the editor side what that character limit is.
