How to resolve large and blurry images on retina and hi-res devices

How do I resolve the blurry image issue?

If you've discovered that your device is higher resolution and running at 200% display then you can fix the issue with the following:

Firstly you will need to have a hi-resolution version of your image and also photo editing software.

Open your hi-resolution image in your photo editing software and resize it so that it is double the size of what you want it to be within your email signature. For example, if you want the image to be 100 x 80 pixels then you will need to resize the hi-res version to 200 x 160 pixels.

Once resized, save your image as either a .jpg, .gif or .png.

Switch to your Email Signature Rescue account and edit your signature or go to your Default Images tab.

Edit the image you wish to replace, then select the file that you've just saved. Once uploaded you will see two check boxes at the bottom of the modal, check the Scale for Retina and HiDPI devices box.

Continue the upload process as usual then install your email signature.

Now that your email signature has been installed you will see that your images are much clearer and appear at the correct size on hi-res and retina devices.
