First, many thanks for this mod/utility!
Im running 1.7.10 with 4.15.7 of your mod installed. Tried it in Chrome and IE9
I am trying to modify the text area size when doing a quick edit. Today its 30 chars wide and 4 rows high.
I found $cols and $rows sets the text area size and are defined in the beginning of the images.php file.
But i can not get it to work if i change the size with $cols and $rows. They still come up 30 by 4 rows.
Am i doing something wrong? Probably!
