Several factors can cause image rendering issues in emails:
Email Client Compatibility: Different email clients (like Gmail, Outlook, Yahoo) interpret HTML and CSS differently, which can lead to inconsistent display of images. Blocking by Default: Some email clients block images by default to protect users from spam or malicious content. Poor Coding Practices: Incorrect use of HTML tags and attributes can lead to images not rendering as intended. Network Issues: Slow or unstable internet connections can prevent images from loading properly.
