You can also find images on pixabay.com. I use this site for my images. I also have photos that I take using my mobile phone.

You can add the images to your website as you edit your post/page. Or you can add to the media library first. Then as you create your post/page, you can insert the image from the library.

Let me know if you need further help?

I create and use my own images (cake decorating niche) and I include a few of the free ones that WA has through site contents.

However, like Alena said shutterbox seems to be the most commonly used. Which is why I try using my own images, as most of these photo sites are not unique, when other people use them also.

I had to go thru them sites a lot ,and I ended up with shutterbox,but you have to word it right just keep trying. Get your pics to where you need them mine are in download s..youhave your picspost in tact,so go to QUIK
