Theme doesn’t have any code for reducing the Image Quality. But the Uploader crops the image in Free Version. In Extend Version, you can use Larger Image Proportionately to 300px X 90 px which will not be cropped. Suppose, you can use any image with 600px X 180px in Extend Version. That will not be stretched
For Membership Options, please find the Membership Page and the FAQs. We have also sent you an E-Mail. You can continue using the Theme with ONE THEME Membership but you will not be able to download the Theme after one year.
