Self Publishing woes

I have started the process via Createspace to self-publish The Shunammite Woman.  I had very little trouble when I used Createspace to publish my first manuscript with them entitled In Remembrance of Me.  Unfortunately, the procedure for creating the front and back cover has changed.  It is now much more difficult for me at least to construct the cover.  The JPEG photos must be converted to PDF files.  I was able to do that with a free download of Soda which I was able to make the conversion.  To take those PDF files of the front and back cover over to a template for the covers is quite difficult.  It appears I will have to purchase software to get that done.  I've checked for literally hours to find a way without success.
I have attached what I hope will eventually be the back cover of the new publication.  It was purchased from istockphoto.com for the view of Mt. Carmel on the Mediterranean Sea.  Of course this actual photo is actually on the coastline of California.
I hope some interest will be shown for my next post which will have the photo I selected for the Shunammite woman.
