Dumb question - how do you easily insert a photo/image inline with writing text in a post?

For YouTube, you have to use the last icon on the right, the Source icon.
It will display text only but you can see in when you hit "preview". 
Hopefully, you won't have the same problem I have when shrinks the size of the video.

If anyone can figure out why, with my Mac, when I post something from YouTube, it shows the proper size when previewed, but when I hit "post", the screen goes blank (white) and I have to refresh it only to have the video shrunk down in size, every single time.

I know to use the "source" on the upper right and to use "share" and "embed" and "copy" on YT's site but aside from that, nothing seems to work right.

Thanks in advance, if anyone knows, and,

For image posting you need an address of the image to copy and that means going to a site that has a URL address. Using your own photos on your desktop or hard drive won't work. 

I use imgpile to hold/store my pictures, photos and what have you, using their image address. The site is free and easy enough to figure out. Once there, all you need to do is right click the image, select copy image address, and use that URL to post to the image icon (URL address) from above.

After that, you can fiddle with the size until you're satisfied and then post.

Got it. But who's the guy with the boot?
