Hello. First of all thank you to the author(s) for the time and effort put into this theme.
I'm just putting my first post together and I've included an image. The theme showed a thumbnail of that image on the excerpt on the home page. However, when I changed the image in the post, the excerpt continued to show the thumbnail for the removed image. The only way I could find to get rid of it was to delete the image completely from the media library.
Please tell me, what is the correct way to change the thumbnail associated with an excerpt?
Please note that I am not using the "featured image" functionality, (mainly because the dimensions of the images I'll be using will vary enormously). I am asking here specifically about the thumbnail which is auto-selected when an image is inserted into a post without the use of that functionality.
Thanks in advance,
