I am unable to add a photo from my PC that is 114.6 KB. I can get it as an attached file, but no matter what I do I always get the error message:
The text that you have entered is too long (313277 characters). Please shorten it to 30000 characters long.
The text in my message is only a few lines long.
I also tried the [img] ... method which put the photo in the body of the message, but still the same error message.
