Blurry images in Plone Kupu

Question

I use the Kupu editor in Plone3 to insert images in the website, automatic scaling images, and make a smaller thumb with a link to the original image.

This is a tutorial of how we do that: http://www.contentmanagementsoftware.info/plone-book/kupu/insert-image-properties/index_html

Kupu creates a new scaled image (not only scaling with css, but scaling it for real), and the result is that images become a little blurry. I don't know if this issue is related to this document.

The question comes to my mind. Is there anybody who find this issue too? Is there any way to fix it?

I think the only way to achieve a great quality images is scaling them manually with photoshop or some graphic editor. But seems that Kupu doesn't allow to do that. You must swallow with its manners and upload its self-generated images.

Answer 1

Well, a bit too localized, but we find main error. I want to respond in case that any user will be in the same situation...

Kupu scale images to a certain width and height. And later, the css rescaled again a little bigger, making blurry images.

That is the main problem, we reduced an image, then enlarged it browser-side again. We didn't notice until now that there was css behind the kupu implementation and "overriding" (so to speak) our configuration.
