Best Practices for Image Quality
For optimal clarity on retina displays, consider doubling the dimensions of your images
If your campaign is 600 pixels wide, create images at 1200 pixels wide
Compress images where possible to stay under the 2MB limit
Use PNG for designs requiring transparency
Use JPG for photographic content to maintain reasonable file sizes
Animated GIFs should be optimized to keep file sizes manageable
Customization Options
Remember that you can adjust the width of your campaigns to suit your needs, which will affect how your images are displayed. The size will ultimately depend on your unique campaign design.
Feel free to experiment with different dimensions to find what works best for your specific campaign goals!
