how do you change a events graphic to the graphic with a variable file name?

[AceJP]

hey all, basically this is what I want to do
set a variable, 1-7, then change the event graphic to the graphic with the name of the variable (being: 1.png, 2.png, 3.png etc...)

the code i have so far is

$game_map.events[event_id].character_name = '[$game_variables[26]]'

the part in red is what I am not sure of. :-/

follow up, how would I set wich row the events graphic is displayed (1-4)?

thanks!

$game_map.events[event_id].character_name = $game_variables[26].to_s
