Image sizes in the Customizr theme
Customizr includes five specific image sizes for the slider, the grid and the thumbnails.
|Height (in pixels)||Width (in pixels||Used for||Cropped|
I already have pictures in my media library, will they fit to the slider dimensions?
If you’ve just switched to Customizr from a previous theme, you need to recreate your already uploaded images for them to nicely fit Customizr specific sizes. Otherwise, the circle hover effect or the slides might not be displayed properly.
Hopefully, you don’t have to re-upload all your images! There is a fantastic plugin to do that : Regenerate Thumbnails.
The recommended way to modify image sizes is to use a plugin from the WordPress repository.
Generally easy to use, a plugin will not erase your previous images, and automatically generates new images at the theme sizes in your /upload folder.
