Based on your query, I recommend using a combination of DreamStudio and Gamma to create a PowerPoint with a picture book inside but out of sequence.

Firstly, you can use DreamStudio to generate images based on text prompts. This feature can be used to create visual representations of the scenes or concepts in your picture book. You can adjust the style, number, and other elements of the image to suit your needs. Once you're satisfied with the images, you can download them for use.

Next, you can use Gamma to create your PowerPoint presentation. Gamma uses AI to help you create presentations, memos, and other documents. You can input the text for your picture book, and Gamma will take care of the rest. It formats, designs, and even suggests graphics and text for your slides. You can then insert the images you created with DreamStudio into the slides.

With Gamma, you can also customize the order of your slides to create an out-of-sequence picture book. This could be a great way to engage your students and encourage them to think critically about the story or concepts being presented.

In conclusion, the combination of DreamStudio and Gamma can effectively address your needs.
