An easy way to make a smooth image transition for a background in CSS - how?

Question

css

Tell me if there are online services or at least instructions for Photoshop aimed at blurring the edges of the image so that it can be inserted as a repeating background in the layout block. Problem example: https://jsfiddle.net/crggjs5d/ . The background with bees is an ordinary picture and its sides do not match each other. How can I blur the sides of the image so that the result looks normal?

Answer 1

1. How will blurring help?
2. Here, usually with pens, they make the picture cyclic.
3. It is difficult to loop your picture in principle, as there is a perspective and it is at an angle.
Solution: find a picture that can be looped.
