Dealing with images in multi-column HTML email design
When it comes to multi-column HTML email, images play a highly important role but your should take into consideration that they are not actually send out as part of an HTML email. They are usually hosted on a web server available over the internet because this will ensure that your images can display whenever someone opens up your email.
Typically, to make it easier to maintain your HTML email, you place your paragraph tags on a single line. Images are a little bit different given that if you put an image on a single line within an HTML table data cell, older versions of HTML software will add a gap. Therefore, it is best to inline all your image tags within the table data cell so that there is a single strain of copy. Besides, you images must be sized properly before sending so you must include the dimensions for each image within the HTML code.
