Next time, if you could remember to credit your photo sources, it will lessen the chance that someone will flag your post. (I haven't, don't worry!)

If you structure it in your post like this:
Image from [ pixabay or whatever ] followed immediately with ( url ), then it will even be clickable. (omit all the spaces I added to the code and it should work.) - also, make sure that the pictures you use are, in fact legal for you to use - there are many sites with free-to-use images.

Have a nice day!
