Images and Tags

Hi,

I have 3 questions here.

1) I did not lock the tags field for my franchise, but they were automatically copied from the main listing to the sub listing.

2) In my main listing, I entered tags A,B,C….G. On frontend, it displays as
A, B, C,…and G. On the sub listing backend, during auto-population, the tags became A,B,C… and the last tag instead of being G, it became “and G“. So on frontend, I have a funny looking presentation of the tags being “and G, A, B ,C …and F”

3) Is there a way to lock the image field for franchise listing so that we only upload one image for multiple franchise listings? That will help speed up the website since we’re only uploading and reusing the same image?

Thanks!
