I dont think WE can change that also be nore specific maybe send a picture of what you want chnaged and I/we as a community can guide you!
I can tell you that if you want to resize your image there will be code in the description that says [width="" and height=""] if you change those blanks it will resize
You can’t, request grazer to do indie featured things like that.
Unless he put that indie feature in place while he had indie and he just wants Grazer to change it now that he doesn’t have indie. Which seems to be the case here
(Although I’m not really sure about the whole “changing the color” thing, but Grazer could definitely remove the customized background entirely)
I think an option to reset a page to default colors could be nice if you lose your indie sub.
But yeah, changing colors is purely an Indie feature.
