Base64 images do not display correctly in Timeline (Freedom)

Hello,

This is a known issue related to base64-encoded images. 

They aren't supported in most web email clients (including Gmail) and are completely blocked in Outlook. Apple Mail is one of the few clients that does support them. Such emails also influence the site's performance, as the email size becomes larger if it contains base64 images. 

We have a few recommendations for you on how to avoid this behavior: 

1. Increase the system setting (create it if it doesn't exist) for LargeSizeEmailValue and LargeSizeEmailValueInFreedomUI. 

2. Enable LargeEmailsInTimeline.DisableEmailPreviewLoader feature. 

Please, consider replacing base64-encoded images with others, to improve the overall performance value of your emails. 

Best regards,
Ivan

Hello Ivan,

We will follow your recommendation and host our images on external servers, this will also improve our deliverability.

I added the LargeSizeEmailValueInFreedomUI parameter to the system settings but now when I click on "see more" I have an error in the console (image attached) and the system does not show me more of the email.

Otherwise, could you please tell me how to enable the LargeEmailsInTimeline.DisableEmailPreviewLoader setting? I can't find it.

Thank you Yvan !
