RE: Fake Card Resources and Help
There are a few ways to render something.
The first, more professional, way of doing it is to carefully cut out an image from another using the lasso tools. If you're good at it then you can cut out some really good renders but it's (very) difficult and time consuming to master. However there are things like the magnetic lasso tool which makes the job faster.
The second, easier, way is to use the magic wand tool to crop out any backgrounds. This works best for simple backgrounds though so if you're looking for a more spectacular image then you'll just have to learn the ways of the lasso or hope you come across it in a search.
