You must enable picture caching in order to preload pictures into the cache or to cache pictures at run time. You enable picture caching in the User Preferences Dialog box, shown in the figure below.
If you disable picture caching, the most recently used cache is disabled, no pictures will be preloaded, and all pictures will be fully closed when the file is closed.
NOTE: Picture caching, by default, is disabled when you upgrade from a previous version of iFIX to the current version. If you are installing iFIX 2.6 or later for the first time, picture caching, by default, is enabled, with a default cache size of five.
Most users will not notice any difference in the way the system behaves with cache enabled. However, if you have done extensive VBA scripting in your application, there will be a few minor differences in the system behavior. If you are upgrading from a previous version of iFIX, you should review and understand these changes before enabling picture caching. See the Making Changes to Pictures at Run Time section of this document for more information.
