Excuse me, as an ordinary user, I noted that there is a clear discrepancy. I twist the mouse wheel, the status bar in section 3 tells me that size of the image in the hover box is changing, but in fact it is not.
Before that, I received an answer: it says, my friend, turn on the option "adjust size" and you will be happy. I don't know why I need to enable this option at all. In principle, everything should work without it. In addition, an ico file differs from a regular image file only in that it has a lot of images, a lot of icons.
When solving even a very simple question, there can be a lot of nuances and it is better not to discuss them, because I will not be able to take into account all the nuances.
My first task is to inform you that there is a clear blunder, and if it is not so, then write to me that it is not so.
