How to Resize a Photo or Logo in Paint
Once a logo/image is uploaded to your form or image manager, it cannot be resized from within DonorSnap.
To change the size of your image, you will need to use a graphics editor. If you are using Windows 7 or later, this can be done using Microsoft Paint.
First open the image in Paint. Click the Resize button in the Home menu.
For emails, you should not use an image wider than 600 – 650 pixels in order to keep it looking nice on phones.
