Resolution of images in projects
I've been developing multimedia projects for the better part of 15 years now. Best practices in multimedia development generally dictate that images placed within projects should generally be low-resolution (72dpi). This keeps the published files size small and helps minimize the impact on bandwidth, blah, blah, blah.
PowerPoint though seems to be a unique animal and I've never quite understood how it handles images. I'm seeing techniques in a number of Articulate tutorial videos that I would never think about doing with other tools like Adobe Director, Flash and Flex - such as scaling images and doing a lot of image manipulation.
I understand PowerPoint has a lot of these features built in, but for the best possible performance, do the "old" rules apply about wanting to optimize images as much as possible when creating a PPT/Articulate project or is there some voodoo magic behind the scene's that optimizes the images for you regardless of whether you use a high or low resolution image?
