Alternately, a member tip is to upload photos to Facebook and re-save the files. Facebook automatically resizes (compresses) photos, so the file size will be smaller, and of the correct format.
NOTE: Other files (documents such as transfer forms and castration certificates) also need to meet file size and format settings. These specifications are listed beside the upload box. If you continue to experience issues uploading them, we suggest taking a photo of the document and uploading it as an image.
