Hello,
Thank you for getting in touch and I am extremely sorry about the trouble this might have caused.
The image doesn’t have an alt tag, you can confirm this by checking your page source, here is a screenshot for your reference: https://i.rankmath.com/IUZBzx. Rank math SEO analysis is only notifying you of what is on your page.
The issue is likely how you are adding the image, a page builder or your theme. You will need to get in touch with the tool developer to assist you with this.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
