Dear Bach Pham,
I have checked the page but the problem is not solved yet. Let me explain you again with two different approaches to solve it:
1- You change the thumbnail dimensions in fixed size by css, lets say 250px*250px. Now, if the original photo size is for example 800px*300px, the photo in the thumbnail will be reshaped not proportionally, meaning that the photo is more compressed (resized) in length compare to its width, consequently, the thumbnail look very stupid specially when its a portrait. Although all the thumbnail are in the same size and aligned now!
2- You crop the original photo from its center in fixed size by css, lets say 250px*250px. Now, since the photo is just cropped from its center by 250px*250px, there is no "compression or reshaping" in any dimension of the original photo which makes the thumbnails look clean, aligned and all in the same size.
Now, what you've done as the solution, is "number 1" (explained above), which makes the thumbnails weird, specially in the case of faces. What I am asking for is to solve the problem as "number 2" (explained above) to solve the problem in a proper way!
By the way, it seems the module is not playing the videos! Could you please check that out as well and see if it needs to be fixed too?
I am looking forward to your solution and help.
Thanks in advance,
Pamchal
