You have to open the tty and send a escape sequence to set what are the
top and bottom rows. I believe it is \33[1;30r you have to write to the
tty. The 1 represents the top row and the 30 represents the bottom row.
Since this is by row you figure out how many rows the image takes you. You
do this by taking the image size and divide by the font height then round
it up if you have a remander. This is what you have to pass for your top
row variable. Remember to reset it after exit the program :-)
