You are comparing character array with image matrix that is why you got error

 if(a==imageArray)
      disp('yes');
 end
 % a - Char array
 % imageArray - Image numeric matrix

I think you are trying to compare filenames so replace if condition as

  if(strcmp(a,baseFileName)
      disp('yes');
 end

uigetfile returns the name of a file, not the contents of the file. But imageArray is the contents of one of the files, not the name of a file.
