RSS feed for podcast sizes the episode image to theme's 'post-thumbnail' dimensions

[murray-john]

Expected Behaviour

When an image is uploaded for a sermon or a series, the podcast (RSS) feed should send the fullsize image for each episode (i.e. sermon)

Actual Behaviour

The RSS feed specifies a version of the image resized to match the theme's 'post-thumbnail' dimensions.

Steps To Reproduce

1. Use a theme that sets 'post-thumbnail' dimensions. For example, twentyfifteen sets these to be 825x510.
2. Set a series image or a sermon image that is larger than this. Apple's requirement is for images between 1500x1500 and 3000x3000.
3. Examing the RSS feed's XML and see that the image of an individual episode is a resized one.

Platform

Sermon Manager Version: 2.15.17 WordPress Version: 5.3.3 PHP Version: 7.0.33

Any Additional Info

The problem is here (code pointer). I think the fix will be to specify 'fullsize' as the second parameter to this function.
