EcoPro is a legacy theme from the early days of our company. While we can provide some basic support, I should point out that our legacy themes are subject to crashing with some future WordPress update (sooner than later). It would be wisest to upgrade to PageLines Framework, which has settings for the alignment of the post thumb, and uses CSS3, which is much easier to manage.
Viewing the site in Firebug for Firefox, I can see that EcoPro requires changes to multiple CSS elements to come close to your desired alignment. The way it is coded, positioning the image down also requires a change of the position of the image link, the position of the excerpt and modification of several other alignment.
My sincerest recommendation is to write to firstname.lastname@example.org and ask about any available discounts to upgrade to Framework.
