"If you don't want to add any code, you can change the image layout from Inline to Stack and then re-add the caption in the Title section under the image. Leave the Subtitle section blank. Save.  \n\tThen, under Design / Image Blocks / Image Block: Stack, change the Image Separation slider to 1% or whatever your preference might be. \n "
