gluepoints as character, etc?

[barna]

Hi
Is it possible to create gluepoints as a character? I would like to add explanation to parts of a picture, and have a gluepoint within this picture (anchored to a given percentage of the picture width/height, so that if the picture is resized, this gluepoint is still at the right place).

At the side of the picture there is a text (a long explanation). I would like to have an arrow (connection, line, whatever) from a specific word of this long explanation to the above mentioned gluepoint in the picture. For me the most straightforward way to do this would be to put a gluepoint within this text just before this specific word (anchored as a character, so that if I reformat the text, add something to it, etc, this still remains at the beginning of this word), and make a connection between these two gluepoints.

However, I could not find any way to do this. Is something like this possible?
