The image cache loads images and templates differently. Templates are loaded by the HTML Player on the Web server and are then used to render the HTML for the page. Template files are always loaded locally to the UNICOM Intelligence Interviewer cluster, so the term “local image cache” is sometimes used to describe the location from which templates are loaded. You could also refer to this as the “template cache”.

Images are loaded by the respondent's browser, based on the image's URL in the rendered page. When a page needs to display an image, the HTML for that page will contain an <img> tag giving the URL of they image to be displayed.
