New Captivate - Hotspot widget Image container size change?

You can make it wider in the UI. Select the white area (preferably next to the title of the hotspot text) and you should see handles to resize.

To make it taller, I have confirmed you can edit the designOptions.json to change the height, from a default of 135px. I changed mine to 270px and it shows twice as tall. NOTE: To change the designOptions.json - you will need to be able to open the file as an Administrator; or copy to a non-protected folder, edit, save and using Adminstrative permissions copy it back to the location where Captivate is installed. In all cases, you'll need Administrative privileges to edit or replace.

You will also want to either create a new design option and/or backup the existing option so you can replace, if necessary.
