    Hi Jeremy,

    I’m hosting an experiment, where the participant sees two images 150 ms apart. If I log the time for each image, does this time denote the moment at which the image was loaded or the time that it was completely rendered on the screen. Sorry if this is a weird question; just that 150 ms is very brief so need to make sure that I know what the timestamps indicate.

    Hi,

    PennController preloads resources, which means images should be fully preloaded before PennController executes any print command on them. The .log command you call on an Image element will report the timestamp corresponding to when the .print command on that same element was executed, so that should be when the image was completely rendered on the screen
