A Distorted Hello

For those of you who use the program "Hello" to post pics on your blogs, I need a bit of help. For some reason when I select a photo taken with my digital cam which I have saved in JPEG format...it looks fine on my computer...fine on everyone else's computer...and fine when I use "Hello" to select it...but when it actually uploads to my blog, it is distorted. Any ideas on how to correct this? I've tried resizing the pics...to no avail.
