Larger images into Thunderbird

[nandit]

When inserting several larger images (JPEG, 1.4 MB, 1770x2440 px, 300 dpi) directly into the message body (i.e. not as an attachment), Thunderbird crashed and the draft of the written message was not saved.

Is there a limit to the maximum size or format of an image that can be inserted directly into the body of the message?

I am using THB release 140.6.0esr/32-bit, OS Windows10Pro/64-bit
