Hi, it looks OK, but when I click on the source, instead of opening the site - pixabay, it downloads the picture.
I made several edits in my first comment, sorry if I mislead you.
However, the link for the first photo that you have to put between these brackets ( ) is - https://pixabay.com/photos/spring-bird-bird-tit-spring-blue-2295434/
The link for the second photo is - https://pixabay.com/bg/photos/%D0%BF%D1%82%D0%B8%D1%86%D0%B0-%D1%80%D0%B8%D0%B1%D0%BE%D0%BB%D0%BE%D0%B2-%D0%BF%D0%B5%D1%80%D0%B0-%D0%BE%D0%BF%D0%B5%D1%80%D0%B5%D0%BD%D0%B8%D0%B5-beaj-1905255/
I think I know what confused you. When you find a photo you would like to use, did you copy image address?
In this way by pasting it on your post, you only show the image, but not the source.
The source is the actual internet link.
I hope this make it a bit clearer. 😊
If you still have doubts, let me know.
Any other questions, feel free to ask. 🙂
