Step 1: Click The Insert Image Icon
Click the "Insert Image" icon in the top menu (see picture).
A new mini window will appear.
Step 2: Upload your image
Click your file image and press "Open" (or double click the image).
Note: If you want to upload more than one image just hold down Control/Command while selecting your file images. Press "Open" after you have selected all your images.
Your image/s will now show in your mini-window. Click all the images you want uploaded into the post so they are highlighted with a blue border, and click "Add Selected".
Your picture/s will now be in your post. But we're not done yet!
Step 3: Edit Image
To change the size just click on the image.
You will see various options come up in a bar.
To resize, click on either "Small" "Medium" "Large" "Extra-Large" or "Original Size". Most pictures will fit nicely with "Large" but you can always preview your post to see how it looks on the page.
You can also align your image to the left, center, or the right in this options bar. Your text will wrap around the image if you select left or right. (Note: I have selected Center in the example image above so the text in bumped below).
And you can also add a caption to the image for additional info. E.g. "Click to enlarge".
Note: When a reader clicks on an unlinked image, it will automatically be enlarged for them to see (see picture).
You now have a post image!
