Are you an Outlook user and have noticed that your images in your email or signature are too large even if you have selected a custom size in LeadSimple? Learn why this happens and what to do about it.

Why is it happening?

LeadSimple allows you to add images inline in your emails and email signature. After uploading an image, you can resize it by clicking on it and selecting either a preset option or a custom width. This will resize a larger image to the size you want it to display in the email or signature.

However, Microsoft Outlook does not always respect this new custom size. In the desktop Outlook app, it often displays the full size image rather than the new custom size you've selected in LeadSimple. (Note that Outlook on web does display the correct custom size.)

Obviously, this is a problem if your images are large, especially if you use Outlook on desktop or if any of your leads or clients use it.

How do I fix it?

To keep Outlook from displaying the full-size, large image, the fix is to use a smaller image in your emails. You may need to resize the image yourself before uploading.

Then, re-upload your image to your email signature. Remember that you want the image to be the right size and not need any resizing after uploading.

Resizing images on Windows

How to resize an image on Windows using the Photos app:

The Photos app should be the default photo viewer for nearly every image type in Windows.

1. Double-click the image file you want to resize to open it in Photos.

2. Once it's opened, click the three dots in the top-right corner, then click "Resize."

3. A small pop-up will appear, offering you three preset sizes for the picture. Pick one of them, or click "Define custom dimensions" at the bottom.

The preset sizes are measured in megapixels.

4. If you picked custom dimensions, a menu will appear that lets you set exactly how big you want the image to be. You can also choose how high quality the resized image will be β€” higher quality pictures look better, but have a bigger file size.

If "Maintain aspect ratio" is checked, then you only need to change either the height or width, and the other dimension will change automatically to match it.

Set your new dimensions, and then click "Save resized copy."
