I've read maybe 25 posts about this issue and have not found a solution.
Here's my problem:
I'm striving for the best image quality down here.
My product pngs are beautiful crisp and I lossless processed them from 90KB down to 20KB each with Image Alpha.
I upload them to Presta.
Now the quality is not crisp anymore, but still acceptable, and I hoped to figure this out one day,
but their size is now: 250K.
I'd like to switch any image processing completely off and only use my original pictures in the product view.
They are already perfect!
But how? Has anyone figured this one out?
I don't believe, it's my settings.
The settings in my image preferences are:
product image width: 200px
product image height: 248px
(original)
For quality I use: jpg: 90 and png: 0 and changed from jpg to png because of the background that's added to the jpgs per default.
Why do we have to accept this Presta-behaviour?
It's the only downside of this excellent software.
(I use Presta 1.6.1.6)
