Candy Cart gives you the option to customize the upsell pop-up with a cart icon you like or your own logo. The icon size is 25x25px, so no need for too big pictures.
To use your own image or store logo, the suggested workflow is to upload it to your Shopify account. To do so:
Go to your Shopify admin > Settings > Files
Click on the Upload files button at the upper right corner of the page to upload the image from your computer
Once uploaded, copy the image URL by clicking on the link icon.
4. Go to the Candy Cart app dashboard and click on the Settings tab.
5. Paste the image URL to the Icon URL field.
6. Click Save.
NOTE: Did you know that there are other ways to upload images or files needed for your store? Learn how to use Metafields, Theme Editor or Rich Text Editor for that.
