I should think the problem is still how to add 23-سمیعی_ادیب to an image, because that's the error message you get when you fail adding something to an image.
There is a problem for us ordinary WikiTreers with helping out - since that profile is private we cannot see what happens. Somebody with admin authority needs to look at it.
I took the liberty to add one of the open profiles with left-to-right characters to an image of mine. I just checked that it worked and then removed the image again. It did work.
I used copy-paste and was careful not to get any extra characters in what I copied.
