Hello Jef Goris,

the length and width of your picture (in pixels) both must be a number that is a power of 2.
A "power of 2" is any number that can be built with only multiples of 2

• 2
• 2*2 = 2 to the power of 2 = 4
• 2*2*2 = 2 to the power of 3 = 8
• 2*2*2*2 = 2 to the power of 4 = 16
• 2*2*2*2*2 = 2^5 = 32
• 2*2*2*2*2*2 = 2^6 = 64
• ... 128, 256, 512, 1024 ...

you get the gist 

The error message in your screenshot suggests, that your image has a length or width (or both) which doesn't follow that rule

Kind regards
Goetz
