When adding images for use in a section, does the theme provide a way to set the opacity for a given image?
For example, on the Bike site, toward the bottom, in the Statistics section, I see 4 floating boxes that have a transparent background. Where is the setting to adjust the opacity? Can the opacity be set for the overall image background?
About the opacity that you want to set for image on the section you can use Background Overlay option. This option available on each Section Background Type. For more detail you can visit our documentation right here http://support.jegtheme.com/documentation/visual-composer/ and jump into Section Background Type section.
