Switching to no medium-size photos
I would like to make a change in the way my photopost gallery operates so that I will only have a single size photo.
I have been running like this for years:
Max allowable image width=800
Max allowable image height=640
Trigger medium height & width=641
Save and display medium and large images?=yes
Q1: If I turn off "Save and display medium and large images?" what happens to existing medium size images?
Q2: Will I need to rebuild images or manually delete intermediate sizes from the database, or what?
