Why images are not loaded

For signatures:

For performance reasons the immediate displaying of the signature of a new SignBase view is limited to a certain amount of images (as specified by the system administrator). If this amount is exceeded, the Single Magnifying Glass icon is displayed for every signature instead.

For other images:

For the same performance reasons, the immediate displaying of all images of a view is disabled, except for single images such as Check Images or Snippets in the Document View. Instead of each image the Single Magnifying Glass icon and the Multiple Magnifying Glass icon are displayed.
