I’ve answered this question a few times now, so I thought I’d add layout the instructions here. I will focus on the uploading of images and linking them while you are writing the post.
Before starting though, there is already a very good video showing this process on Youtube.
Just below the writing window you’ll see the following for uploading images.
Click Browse and locate the file on your computer you want to upload. Once you have chosen the file, enter its title and description. Make the title descriptive as well so this image will be easier to find later if you want to use it again. No click the Upload button. You will see the following in the upload area when it is finished.
You are now ready to add the image to your post. Click the “Send to editor” button and the code for the image is placed in the writing area.
Now finish editing your post and you are done.
