Troubleshooting
The curves in the image look jagged after uploading.
What happened: Jagged edges appear when an image is resized and the smooth curves are represented with fewer pixels.
Resolution: Shrink the image and crop the canvas to 430 x 120 pixels then upload the file again.
The image appears to have a grid-like pattern after uploading.
What happened: CMYK or indexed-colour images can cause distortions when they're converted to RGB colour.
Resolution: Switch the colour profile to RGB then upload the file again.
