Gmail Inline Image Fit - is a small extension that can help you solve the problem of horizontal scrolling in Gmail messages. This small extension gives a lightbox view of images and video inside the message body of Gmail.

With a lightbox, we will be able to view the complete image, even if it is a large screenshot or an online video. It will allow you to browse through your conversations in a new way.

As you have seen before in the chat section, we already have a lightbox view of images in Gmail. It is created with an enlarged view of the image so we will not have to scroll through the message body.
