In .mat files having any variables name means its easy to use imshow function

The reply "testdata = 1x67 struct array" reveals, that a struct array is replied. So please try:
storedStructure = load(fullMatFileName)
for ii = 1:numel(storedStructure)
figure; % Open a new figure
image(storedStructure(ii).image);
end

It does not matter. If there is no field of the structure "storedStructure" called "image" then the reference to storedStructure(ii).image will fail.
I suspect you have different code, a different mat file, a different question, and should have asked this in your own discussion thread.

image() works under the following circumstances:
- data is uint8, uint16, uint32, uint64
- data is int8, int16, int32, int64
- data is single, double
- data is logical
- data is 2D array
- data is 3D array with length of third dimension is 3
image() does not work under the following circumstances
- data is char, string, cell array, struct, graphics object
- data has complex components, even if the components are all 0
image() does not normally work for objects (in the object-oriented sense), but it is not out of the question that the designers of the object might have created an image() method

storedStructure = load(fullMatFileName);
image1 = storedStructure.image1; % or whatever it's called.
image2 = storedStructure.image2; % or whatever it's called.
image3 = storedStructure.image3; % or whatever it's called.
imshow(image1, []);
imshow(image2, []);
imshow(image3, []);

Use the load() function. But you saw my answer so I'm not sure why it's not working for you. What went wrong?

I"m getting this error:
>>image1 = storedStructure.image1;
Reference to non-existing field 'image1'
why?

You need to initialize frame counter somewhere of course. Did you do that? Do that before your loop starts. You might call getsnapshot() instead of getdata().

Enclosed is the complete script. I'm getting an error "A timeout occurrred during GETSNAPSHOT".
I want the script to take an image whenever the hardware is being trigged and I only want 5 images for now.
