save images inside a for loop at uneven intervals

Hi,
I am trying to save images inside the Img array that is generated inside the for loop at uneven iteration numbers. For example sometimes image generated at 10th iteration, while sometimes it's at 150th iteration. How to handle this?
for i = 1:a
B = some process % my image
Img(:,:,) = B
end

Here's one way that may work for your particular task:
Img = zeros(0,0,0);
for i = 1:a
B = some process % my image
if ... % if some condition says to store this B in Img
Img(:,:,end+1) = B;
end
end

Maybe something along these lines:
Img = zeros(0,0,0);
last_stored_time = ts(1);
for i = 1:a
B = some process % my image
if ts(i) - last_stored_time >= 200
Img(:,:,end+1) = B;
last_stored_time = ts(i);
end
end

If you don't know in advance which and how many loop iterations you'll be storing, it would be best to accumulate them in a cell array, and then post-concatenate:
Img = cell(1,a);
for i = 1:a
B = some process % my image
if ... % if some condition says to store this B in Img
Img{i} = B;
end
end
Img=cat(3,Img{:}); %empty cells are discarded
