You may notice that some images on a document have links to click and enlarge while some do not. The reason that these images are different is that the full-size dimensions of the files is different from one another.
Each Webonizer site sets up a standard width of a file that decides if there will be a link to enlarge a file. If your image width is equal to or smaller than that width, your image will likely not display a link to enlarge—even if the page displaying the image is not displaying the image at its full-size.
For example, if your Webonizer-enabled site has a standard width of 260 pixels, then your image will likely only display a link to enlarge if the original file you loaded is wider than 260 pixels. This is true even if the page displaying your image is only showing the file at smaller size (e.g., 150 pixels).
To make an image clickable, delete your file and reload a larger size of the image. Currently, Webonizer does not display the standard size of images, but the default size is 200. (The Villas plugin has a standard width of 260 pixels). The next release of Webonizer will alert you to the site’s standard image width.
