Maximum number of QGeoMapObjects within a Map?

[QtQueries]

Hi

I am displaying a Map with several QGeoMapObjects within my application (MapImages in fact). Up to 200 or so works just fine, however beyond that (~1000) there is a large delay in loading all the images on to the map, and another large delay after unloading the screen containing the map. This happens even if all the MapImages' source properties point to the same file.

Is there any way around this, or is there a recommended maximum number of MapImages on the screen at once?

Thanks
