Make sure that the image has the correct format and size. The acceptable file formats include: .jpg, .gif, .png with a size no larger than 5 MB.
After uploading the photograph, a window where you will be able to crop the picture should open. After clicking “Save”, the picture will be visible on your profile page.
If the cropping window doesn't appear, check whether you have ads and pop-up windows blocking add-ons installed in your browser, e.g. AdBlock. If so, turn them off when uploading the photo or add GoldenLine to the exceptions list and refresh the page.
