Hello, I have problem with my first banner on home page.
There is 2 or more second till the pictures will appear. I made even smaller filers to test it. Its the same even when files are 20 kb size. The same time is when i use one picture than two in carusel
Is there any way to make instant show banner pictures like other sites have? What is my issue?

The delay you're seeing is the time to load the plugin.
1) Rather than doing a carousel / banner plugin, just show a single image, coded directly into your theme without loading a plugin.
2) If you insist on using a banner to show multiple images, you could code it custom without using a 3rd party plugin, this would be faster, for example if I were coding a banner like that I would have the first image show instantly, then lazy load the other images in the carousel.
3) It's possible that the plugin has code + is reliant on a 3rd party library, like jquery. Some theme developers load libraries or scripts further down the page to appease scores in performance analysis tools, but the negative affect is a slower peceived loading time. If this is the case in your theme you can experiment with not deferring those scripts that need to load the banner.
If you need help with any of these solutions contact my team at speedboostr.com/contact. We do stuff like this all the time.
Yes, have the image load right away instead of waiting for the plugin to load, or if it's wrapped in a plugin that has to generate all the banner code at first, you could put an image there and then hide it when the banner loads. If you custom code it anything is doable.
