How can I use my original pngs throughout the shop?

[wol4]

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)
