How to enlarge image widget?
I have added a field image at the left bottom of the sale order form by creating a binary field into the sale order form colummns and adding a field widget="image" into the xml view of sale order form. The image appeared well but i want to know how i could enlarge it because the image size is too limited. I've tried to add an img_height and img_width parameters into the xml view but the square allocated for the image don't enlarge. Do you know another way to make it?
