When refreshing a Skylight, the underlying URL is loaded and a snapshot is taken.
It is then possible that there are elements on the page that take longer to download than the report. To manage this, there is a function to delay the snapshot, called “Page Load Delay”
Page Load Delay¶
If there are custom images or graphs on the report, it is possible that these will take longer to download than the report - and the report will be ready before all images have downloaded - resulting in the image not showing.
In this case, it is possible to force the Skylight to wait an extra period of time, to ensure all images are downloaded and properly show in the updated Picture.
Change this to a larger number for a longer delay.
