We will reject an image with an unacceptable or unrecognizable file extension or file type.
We accept JPEG (.jpg), TIFF (.tif), .PNG, and .GIF file types (JPEG is preferred). The extension can be upper or lower case.
Verify that your file is in one of the accepted formats by right-clicking the image file and selecting Properties. If it is not in an accepted format, open the file in an image editing program and Save As the correct format or obtain a file in the correct format from the photographer or scanner.
