Hi Sarah,
I'm wondering if the "100 people" are from the Storyline character pack perhaps?
I would suggest, once you get your people images resized/cropped/etc. to your desired size, optimize them to that size. If you look at the size of any image and it says it's current size is anything less than 100%, you are showing at a smaller size, but the file still retains all the data needed to show at its full size, which with many images can slow things down.
Optimize image(s):
- Save your image at its current (edited) size (right-click > export picture > save picture).
- JPG for anything not requiring transparency
- PNG for transparency only
- Import that image to your stage, using your existing image as a placement guide, if needed.
- Delete the original image.
Hope that helps.
