Answer 1

Here are some pieces that may help you 1. Iterate over each character

local str="Something"
for i = 1, str:len() do
    print(str:sub(i,i));
end

2. load image

   local img = display.newImage("images/" . letter . "1.jpg");

if you need anything specific ask here

Answer 2

To iterate over each character, try also this:

local str="Something"
for c in str:gmatch(".") do
    print(c)
end

(Actually, this iterates over each byte in the string, which may not be what you want if the string contains Unicode characters.)
