I’ve recently made a prezi with lots of portrait pictures of individuals in it, which I’ve pulled off the web. Unfortunately I didn’t check the file sizes of the different images, I just kept copying and replacing content. Now I’ve got a prezi with 30+ images and some of them may be too large, leading to a clunky presentation. Is there anything I can do to easily optimize this, or should I really download every single picture to my harddrive, resize it, and re-upload them?
An “auto-compress” option to delete cropped parts of pictures and compress them to a manageable file size would be really helpful.
