Hello, other will be more willing to help you if you write in English.
Here is the question translated using Google:
hello …. why is displayed in different sizes in the slideshow images?
I visited your website and I saw the issue you mentioned.
This slideshow plugin is a plugin to show images on your website with some (sliding) effects. But this plugin is not an image editing software. You still need to manually crop all the photos to a same width and height using an image editing software before you upload them to your website.
For example, I saw one of the image size is 2.448 x 3.264, while the other is 642 x 856. You should make all of them same size, perhaps 600 x 800.
If you can’t afford pricy image editing software, you may try GIMP, which is free. Or you can use free tool from Windows – MS Paint, which usually can be found at: Start Menu > All Programs > Accessories > right click Paint. Also I suggest not to use large size photo (2.448 x 3.264), it will make your website become very slow to load.
