Hello Dear Christopher,
Thanks for your reply!
And i have seen this answer in other 's help post before and I have tried the other day. But it does not work.
And I would prefer to solve this problem from non-code way as I am not a technician so I would meet this problem often in the coming days when we try to post new blog.
So now I tried to change the size of photos to be the same , in theory , it should be the same height now. And it works. So I will handle this in this way .
Thanks for the attention.
