Changing sizes of header boxes arrows - How?

[arbocenc]

Hi!

 

How can I change the header boxes arrows?

 

My problem is that I arrow is too small, and when I change it by one larger (downloaded from other nice shops) I've still see it small. It seems how image size is predeterminated (I can't find in which file).

 

Thanks a lot,

 

Joan

I can answer my own question :lol:

 

I saw deformed arrow because my cache "remember" old sizes, now it's all right (my cache has lost part of his memory :-)

 

See you inside one of my lettuces ;-)
