I'm sorry for the trouble you had getting your new cover image to appear on the website.
I reviewed your cover image and found that its dimensions are outside our recommended size. For ideal conversion results, we recommend resizing the image to fit within 1600 x 2560 pixels.
Before you upload your resized cover image, you'll also want to make sure that it meets these guidelines:
- Minimum dimensions of 1000 pixels in height and 625 pixels in width.
- Minimum 72 dpi (dots per inch)
- RGB color profile
- An ideal height/width ratio of at least 1.6:1
After you upload your resized cover image and click the publish button, the changes will take effect on the website within 72 hours.
