If you have noticed that your images are appearing squished when viewed in the preview window or in an online version, then it is likely that the image is larger then our maximum image limits of 1200px (width and / or height).
These settings are in place to help with the look of your emails in older email clients (particularly Outlook), which automatically add line breaks every 1700px (in height) or so.
If you find you have uploaded an image that is over 1200px in size that is not looking correctly in online versions, please use smaller images within your message.
