2. In general, Settings > Media you can set the pixel sizes of the media images that are added to the website.
If you upload the images all in the same size, they will be displayed in the same size according to what you’ve set in the media settings.
In the page you sent, you uploaded images in different sizes.
4. Are the settings you’re referring to added with a plugin?
5. We give here technical support and unfortunately I can’t give you the specific code to do this. But you can add a title widget and give it a link.
7. Unfortunately I dont. But try looking it up in the plugin’s support.
8. Can you send me a link to the page?
9. In slideshows unfortunately there isn’t a way to set that, but in galleries > slideshow layout, you can unmark the ‘Slide Auto Height:’ setting and then all the images will be sized to the grid.
10. We don’t have a limit for menus, it has to do with WordPress itself.
