If you are having trouble uploading an image of your document, make sure the image is clear, in color, without any edges cut off, and no shadows covering any part of the document. Try slightly angling your position to catch surrounding light. Steady the image by placing your elbows on a firm surface, like a table or desk, while taking the picture. You might also achieve better results if you use a webcam to capture the image, rather than uploading one.
