I need some advice on posting a jpg

I've had some odd problems recently with an occasional distortion in recently recorded tracks. The best way to explain what I'm seeing is to post a picture of the magnified wave form in hopes you folks can confirm or deny my suspicions of the cause of the problem. I have a jpg of the wave form I'd like to include in my post but this forum will only let me post a link to a picture within a message. Where do you folks post your pictures and how do you go about linking them when you include a picture in your posts. I'd prefer something fairly simple, so I can get back to the fun stuff.
 
Thanks in advance,

Thanks Legion. I'll give that a try.
