Local Images
If you decided to use images from the POS(computer) that is stored locally, and do not want to use remote images, you may use Local Image.
Find out your local folder path.
If you do not have a local image folder at the following path, create a folder and name it "IMAGE" to the path.
Place all your wanted images to the IMAGE folder.
Go to POS and you'll be able to see all the pictures you've put in the IMAGE folder.
Click the one you want to use.
*Note 1: Some of the image selection option, you may not be able to use Local Image option. In this case, please use Remote Image
*Note 2: Image sizes usually auto-fits the screen, but if you want to minimize the blurred image effect, please try to refrain from using low-res images.
