Hi Jess,
If you really want to take your photography seriously start using Adobe Lightroom. It might be confusing at first but it’s in your best interest to learn a program like that. If you look at this page there is a series of free video tutorials on how to use adobe lightroom: http://tv.adobe.com/product/lightroom/
With lightroom you can manage, edit, print, and share your photos all in one application. It really is the best photography software.
Picmonkey probably does it for SEO reasons. I don’t think there is a way to disable it but honestly I really don’t know.
If you have any questions just write back here or email office@photographyicon.com
Thanks!
