You don't need Photoshop or some other advanced piece of software to resize a large number of images at once. You can use Microsoft Office Picture Manager which is part of the Office suite.
Microsoft Word allows you to add the comments to text, images or basically anything included in the document. It's a great way do review a document and suggest the changes that should be made.
If you want you can turn any Microsoft PowerPoint presentation into a video so you can play the presentation on a computer that doesn't have Microsoft Office installed.
