Need help applying design to template.
Hey, I'm wondering if anyone can help me out. I'm trying to put my design on a template and prepare it for submission. This is my first time trying this and I'm new to Photoshop. I'm wondering if anyone has advice on how to resize and reformat the image to submission standards while maintaining image quality. I'm also not sure how to apply my design to the template. If anyone could give a step by step walkthrough of these processes it would be greatly appreciated. Thanks.
