How to load and process multiple images

Hi everyone,
I came across the matlab wiki and found this code for loading up multiple images to process them, which I have slightly edited.
However, I am getting the following error
Error using load
Unknown text on line number 1 of ASCII file paganin_000001.tif
"II*"
I am not sure how to edit this code to read these files, I have 100 of these images. Do I need to convert these images from tif to png or jpeg? As I cannot upload .tif files onto here either too.
Any help would be appreciated, thanks.
for k = 1:20
matFilename = sprintf('paganin_00000%d.tif', k);
matData = load(matFilename);
jpgFilename = strcat('image', num2str(k), '.jpg');
imageData = imread(jpgFilename);
textFilename = ['file' num2str(k) '.txt'];
fid = fopen(textFilename, 'rt');
textData = fread(fid);
fclose(fid);
end

Are your original images TIFF or JPG? You don't have any .mat files do you? If not, you shouldn't be using load() to read image files. And I don't think you need both but I can't figure out what your filenames are. Some are tiff files that start with "paganin" and some of JPG that start with "image"??????? Do you have two sets of images? Half are TIFF files and half are JPG files???
Original images are all tiff. I don't have any .mat files. No all files are tiff, please ignore the jpg files.

Try this:
for k = 1:20
fileName = sprintf('paganin_00000%d.tif', k);
if isfile(fileName)
% If the file exists, display it.
imageData = imread(fileName);
imshow(imageData);
drawnow;
else
% Print alert for those files that don't exist.
fprintf('File not found: "%s".\n', fileName)
end
end
