Concatenating Images multiple times in a Loop

Hey everyone,

I have a text file in which I have 1000 lines. Every line has a four characters, I also have a folder (named Alphabets) which has all the characters in it (0-9, A-Z, and a-z). What I want is to read text file first four characters (single line) and then go to Alphabet folder, pick those four characters concatenate them and save them in a particular directory. I also want to resize image back to 140x60 pixels. This is what I want to do for complete text file so that by the end I have 1000 images stored in a specific directory. What I coded is a lot of if else conditions and I realize that my code is not efficient so I thought of asking help from experts. Thank you very much!

Regards,

Give an example, and attach the text file. In the meantime, you might want to look at fgetl(), and dir() or imageDatastore().

I have attached text file and here is the sample image that has been generated by concatenating four characters, then manually resized to 140x60 pixels.
