Email Signature - This image is too large to display
SOLVEHi @Dave75 here's what might be going wrong and how to fix it:
Check actual file size (KB/MB), not just dimensions: Even if the image is 100x90 pixels, if it's a high-resolution PNG or not optimized for web, the file size could still be large (e.g., over 1MB), which can trigger the "too large to display" message in some email clients. Try compressing the image with a tool like TinyPNG or exporting it as a lower-quality JPEG or optimized PNG.
Host image externally with reliable URL: Avoid embedding the image directly with data:image/... base64 encoding or hosting it on a slow or restrictive server. Instead, upload the image to HubSpot's file manager or a fast-loading CDN and use the public link in your <img src="">.
Use absolute URLs only: Make sure the image source (src) uses a full https://... path. Relative URLs or links requiring authentication can cause loading issues in email clients.
Avoid large DPI settings: Sometimes even a small image dimension-wise may be tagged as “large” due to high DPI (e.g., 300dpi). Try exporting your image at 72dpi, which is standard for web/email.
Email client limitations: Some clients (especially Outlook or mobile apps) have quirks with how they interpret image size and HTML. Try testing your email in multiple clients using a service like Litmus or Email on Acid.
Hope it helps

Email Signature - This image is too large to display
SOLVEHi @Dave75! Are you using custom html or html from the HubSpot signature generator?
Have you tried replacing the file type? Maybe uploading some screenshots of the html will help provide valuable context.
