问题
I am trying to use the ionic resources --splash command, I have a splash.png file saved in my resources folder as well as in the root of my ios and android folders, and it is 2208 x 2208 which is the advised size. But when I run the command I get the following error
"Invalid upload: unable to read uploaded image"
I have added the splash screen preference in my config.xml. Is there more conditions that they didn't specify?

I got the same error when uploading an interlaced .png.
However after re-exporting with interlacing turned off ionic accepted the file fine.

I just realized that the image I had was actually an Adobe Illustrator image. All I had to do was rename the image from .png to .ai and it worked!
For those wondering here is a quick explanation on the difference between the two:
.ai - Adobe Illustrator vector files are scalable both down and up.
.png - pixel files can be scaled down, not up.

Do not try to save your original jpeg image into png by changing the name of it. You have to use png image. For instance, I save my jpeg images into the ionic folder, and change the type of the jpeg file by changing .jepg to .png. However, it doesn't make a real png image. You have to use software to do the type transferring or download the png image.

I had it working in Windows 7 by storing the icon and splash files as psd.

Here is what I was doing wrong:
1 - Renaming a .jpg to .png and hope it works, it didn't. You need to use a .png image.
2 - Using an image with incorrect resolution, most articles mention that it has to be 2208*2208, I kept getting errors for an incorrectly sized image. Using a 2732 * 2732 resolution image worked like a charm.
