Insert an image in vhdl as an array

[triggerman]

I want to insert an grayscale image(8 bpp its ok) as an array in VHDL.I am new to the language so the simplest thing i thought was this :
PACKAGE newtype IS
TYPE vector_array IS ARRAY (0 to 9,0 to 9) OF
BIT_VECTOR(7 DOWNTO 0);
END newtype;

USE WORK.newtype.ALL;
ENTITY test IS
PORT ( inp1 : IN vector_array);
END test;
ARCHITECTURE arch OF test IS
BEGIN
END arch;

The code above has no errors and do what i want but it uses many pins(800).So i want to ask if there is a solution to do the same thing(read an 10x10 array of bit vectors) but with less pins used.

Thanks in advance
