It's my understanding that the image must be in one of these three file formats:
* JPEG (.jpg) * GIF (.gif) * PNG (.png)

The discussion addresses difficulties in attaching images to forum questions via email submission. It is clarified that acceptable image file formats are JPEG (.jpg), GIF (.gif), and PNG (.png), while BMP and TIFF formats are unsupported. For diagrams, GIF and PDF formats are recommended, with PNG also suitable due to its "GIF-like" mode. Users are advised to ensure the file extension is correctly set (e.g., ".jpg" instead of ".JPEG") and to consider image size and the platform/browser used for uploading (such as Windows or Mac with Firefox, Chrome, or Internet Explorer) as potential factors affecting attachment success.
