I received a message saying my posting an image over typing up a message to my question invalidated the thread. Since math in general relies heavily on using symbols, it is easier for me to write out my question by hand. I made sure the quality of the image was high, and that my handwriting was legible. I'd just like everyone's take on this rule. If it must be enforced, can I follow a format that allows me to post a picture to my question without invalidating the thread in the future ?
