Using the slideshow particle, I find that images loaded into the module that have text are displaying slightly enlarged and therefor blurry. Here is the example.

See the 5th image entitle Planning Ahead. The, here is the image by itself. You can see how crisp it is compared to the slider.

What am I doing wrong, and how can I advise my client to size images so they will appear clean and crisp? They use services like Canva to create images and banners.

Thanks much for your support!
