Recently, I was tasked with building an email invite to ImageCon, Cloudinary’s annual image and video management conference. This email was destined for the inboxes of almost our entire database, and as you can tell, it wasn’t going well.
After staring at the preview in disbelief in Marketo for a few seconds, I quickly cycled through the seven stages of grief. Actually, I got stuck on the first one – anger. I mean, just take a look at this monstrosity:
Not pictured: me throwing things in a fit of rage.
It’s never a good sign when your images make you wonder if you’re long overdue for a trip to the optometrist. Considering this email was going to hundreds of thousands of developers – and we are known for our abilities to deliver optimized images – I needed to seriously improve the email graphics.
On the surface, replacing a banner on an email template should be simple. In Marketo, you should only have to find the URL of the image and replace it with one of equal size. It’s a straightforward swap… or at least it should be.
However, with the explosion in popularity of devices with high-resolution displays like the Galaxy Note 7 (ba-dum-tiss), things have gotten a little more complicated for marketers. Our images need to be optimized for the device on which our users engaging with content, while also loading quickly and efficiently.
Well, it turns out that, the 600×200 image I was using was being set to a Device Pixel Ratio DPR of 1. That basically means that you get fewer pixels in your image which, when viewed on a high-resolution display, comes out looking like hot garbage extremely blurry. This effect happens because high-resolution displays can fit more pixels in essentially the same amount of visual space.
It fortunately displayed just fine on lower-resolution devices, but that wasn’t much consolation knowing that many individuals receiving the message would be viewing it on high-resolution devices.
So… much… better.
When you can automatically optimize your images for delivery based on the viewing device, that’s great. When you can do it all within the URL – without having to upload multiple images – that’s even better.
With a small addition of dpr_2.0 to the image URL in Cloudinary, I was able to sharpen the image almost instantly:

You are technically able to accomplish the exact same thing by simply doubling the image resolution. However, with this URL in hand, I can repurpose the exact same image and replicate it across any of our assets and site pages via a simple modification of the URL. This saves serious hassles for me, my design team and my developers a huge headache since I don’t have to bug them for multiple copies of the exact same image.
With that easy change to the URL, I now have a new image that I’m content to send out enhance the email I’m planning to send, as well as a replicable asset that I can modify with minuscule effort. Email is done, frustrations have subsided, a plan is in motion for additional ImageCon assets, and all is right in the world.
Life is so much easier when your images look good, isn’t it?
