How to display certain image sizes when installing Custom Field Suite?

Question

WordPress

Good afternoon, I use the Custom Field Suite plugin to display images in the slider. Easy to add and take out too. However, there are a lot of images and they are in 1920 by 1200, despite the fact that such permissions are not required in the slider, they take up additional space. I also noticed that when adding a picture, the VI creates a thumbnail
file-name-sizeXsize.png. How can I get this size. For example, when adding one picture to the vp, such pictures appear
filename-150x150.png
filename-320xY.png
filename780xY.png
The largest number is no more than 800px and the height is calculated. out of proportion. I would like to output in this resolution. How can I get the names of such files

Hello.
In the template where you display the image, you can specify the required image size.
thumbnail - 150x150px
medium - slightly larger
large - even larger
full - full quality.
You can also create your own size by adding this code to the theme's functions.php:
For example, in your case it will be like this:
(name - my_slider, width - 800, height - 600, cropping - off.)
Then you can use my_slider to display the image a specific size in the place you need
