I use MAMP Pro 4 and Windows 10 to develop WordPress websites on my local computer. When an image is imported into the media library WordPress generates image sizes from this image and places them all in the wp-content/uploads folder, all standard WordPress functionality.

All the images are fine except the original image which does not have correct permissions. When I check Properties, Security of the image, it says "You must have Read permissions to view the properties of this object."

I then have to go through a 7 step process to add Full permissions for the computer user for this image. This is difficult when I have hundreds of images. There are no errors in the Apache log or the PHP file log.

I contacted MAMP support and although they are aware of the problem, they couldn't help me resolve it.
