Most pop-up blockers allow this kind of pop-up. Some, however, reload the page, losing any information the user entered. Some online shops use exit intent popups, for example offering discounts, in an attempt to retain users. [10] Some web based installers, such as that used by McAfee, use a pop-up to install software.
However, "center" sometimes shoves the caption to a 2nd line (under a centered box "[]"), so "thumb|" could be omitted and just hard-code the image size, adding a gray (#BBB) border. Using precise parameters to match other images, a floating-image table can be coded as follows:
