When I receive emails with image attachments (image.jpg for example) it displays in full resolution in the preview pane or message window. It would be nice if the image was resized for display purposes to fit the window or preview pane size so you can preview the whole image.
In the attached screenshot you can see both the individual message window and in the background you can see how it displays as well in the preview pane. Both images were sent as attachments. eMClient previewed these image attachments at full resolution.
