Photos: Generally, JPG is a good choice for photographs due to its smaller file size.
Graphics, logos, and images with text: PNG is preferred for its lossless compression and transparency support.
Aspect Ratio:
Standard Screens: Most screens these days are widescreen (16:9 aspect ratio). Aim for images that fit this nicely to avoid black bars or distortion.
Presentation Environment: If you know the exact screen size where your presentation will be displayed, you can tailor your image dimensions to perfectly match.
Resolution:
High Resolution is Key: Use images with a resolution of at least 1920x1080 pixels. This ensures your visuals look sharp on large screens.
Avoid Upscaling: Don’t enlarge small images, as they’ll become pixelated and blurry.
Commandline Tools: Use the following scaling for consistency.

Color Ramp
To maintain a consistent and eye-catching color scheme throughout your slides, consider using a color ramp based on your website’s primary color, #7F00FF, and gray, #555. Here’s an example of how you might incorporate these colors into your slides:
1. Background Color:
Use a lighter shade of your primary color or gray for the background. This could be achieved by adding white to the hex code, such as #E6D1FF (light purple) or #CCCCCC (light gray).
2. Heading Colors:
Use your primary color (#7F00FF) for main headings (h2).
Use a slightly darker shade of purple or your gray color (#555) for subheadings (h3).
3. Text Color:
Use your gray color (#555) for the main body text. This provides good contrast against a lighter background.
4. Highlight Color:
Use your primary color (#7F00FF) to highlight key words or phrases. This helps draw attention to important information.
5. Link Color:
Use your primary color (#7F00FF) for links. This helps them stand out from the main text.
6. Table Colors:
Use alternating light shades of your primary color and gray for table rows to improve readability. For example, use #E6D1FF for odd rows and #CCCCCC for even rows.
