Question
I get an error when processing images.
Answer
99% of the time the error is caused by one of two things. Either the file size is too big or the color type is incorrect.
The image files must be under 1MB in size. Larger images will cause the tool to time out and throw an error.
The image must be an RGB color image. If you try to upload a CMYK image you will get an error.
