Hi,
thank you for helping me. But i still have some confusion and will be great to fix this issue, because i really don't like to lost that much time for editing and at the end to lost all of my work...
The size of images i have is around: 5616 x 3744 ( depends if i crop something or not ).
The size i wanted for images is: 900 x 600. I am using this size, just because on my website, which is: http://imagestudio.com ( the slideshow match perfectly with this size, but in cases 960 x 640 will have better quality or some improvements for mobile, etc, i can also use it for future ).
This are the settings i am using to resize the photos to 900 x 600.

I have tried to upload the full size image, but seems that maximum size i can upload is 3500 x 3500, so i have resized the image to 3500 x 2333

And finally this is the photo resized to 900 x 600 pixel.

Please let me know if i do the things correctly or what solution you suggest me to use. I have tried with Lightroom, but the image it's even worst than with Photoshop.
Thank you again so much for your efforts to help with my queries.
