Important Email Image Checks – Will Your Design Explode in Outlook?
Email marketing teams large and small usually have a workflow that includes a robust pre-deployment checklist. It includes checks for content, design, functionality, subscriber lists, and much more. Image validation should be included in that list, as well. This means double-checking your HTML image parameters to make sure they’ll display properly on every client. For example, if a subscriber has images blocked on his or her client, failing to set certain image attributes can result in design flaws, or worse, a broken email. Outlook, in particular, is infamous for messing with emails that don’t have image attributes. Image validation may be a routine step for many of you, but that doesn’t make it any less important! We’ll walk you through the important parameters to check and why you need them.

Don’t Rely on that CSS
The image parameters we’re talking about in this post are related to the HTML attributes only and not the CSS that may be applied to your email image. While you may rely on your CSS to set your image parameters, remember that certain clients may ignore that CSS (hi, Outlook). Yes, you may be doing these HTML attribute checks for only a few bothersome email clients but leaving them out could break your email on those clients. It’s important to keep every subscriber in mind and ensure your message is consistent for all audiences.Set Image Borders
The first step in making sure your HTML attributes are up to scratch is to set all your image borders to zero (0). Why do this? Some email clients (older clients, to be honest) will add an ugly blue border around images or buttons with links. With our image validation tool, you can apply border=”0” to all your email images with a quick click. We’ll do the work for you.Set Image Width
This one’s a biggie. An image without a fixed width attribute can get out of control and throw off the readability of your email, especially when the user has images turned off. You’ll often find this problem in – you guessed it – Outlook clients. When you don’t set a pixel width for images, Outlook can blow up the picture to the point where it can take up the whole screen and span beyond the window. This can make text hard to read and overall, create a poor experience for the user. For example, we forgot to set a width parameter for our social icons in this newsletter (the code reads style=" border: 0" alt="Facebook" height="" width=""). In the Email on Acid image validation tool, you’ll notice red boxes highlighting the problem areas:![image validation width issue](https://media.emailonacid.com/wp-content/uploads/2018/11/Image-validation-width-problem.png)
