The easiest way to change font colors is when you write a post, there is an icon that says HTML at the top of the post box. If you click on that you can change the code there to include a <font color=”#hex”> tag and put whatever color you like. You just need to know the hex#. Then click update.
As for images, once you upload them using the upload feature you need to click on the thumbnail image. There are a few features such as “Using Thumbnail, Link, Send to Editor.” Just click on Send to Editor and it will put it in with your post wherever you cursor was.
