A good presentation has images that are consistent in style throughout the deck. Same color palate, same mood, same type of characters. This was very hard to achieve unless you make drastic design decisions: vintage black and white only, pop art cartoons only, impressionist paintings only (remember Ideatransplant ?), or cheesy stock images only.
AI can bring a solution here. Invest time in developing a standard prompt that generates the desired setting for your photo, then apply that same prompt consistently with small variations to get your snaps.
Databases of image prompts are starting to pop up (see a list here, writing this in May 2023) and this trend might well be the beginning of the end of stock image sites and even model agencies.
