Use caption-with-value from <oppia-interactive-image> in RichText

[rt4914]

Currently oppia-interactive-image is used to render images in RichText. We should use caption-with-value from oppia-interactive-image to show a caption below the image in application.

@rt4914 I'd like to work on this. How should I go about it?

@Victor-Titan You can start with ImageTagHandler in utility module. It might be too hard at first but if you get stuck feel free to unassign.

Hi @adhiamboperes can i work on this, i can add the caption-with-value tag in the ImageTagHandler and its related tests. The handler will retrieve the caption from the caption-with-value tag and append the caption as a new line below the image using SpannableStringBuilder
