Hello, is it possible to resize images, but keep the original file format?
i.e. PNG with transparency

use cases:

  • image slider with products (separate upload, or featured items pulled from catalog/directory)
  • product main image (placed on same common background)

Ooops, this was primarily a QUESTION. ;)

Any thoughts and advice? If not possible by configuration... maybe upload of original... and custom call of resize-function and parameters?

I gave you a +1 because it is a good question. And I also would like to know how this might be done.

I checked the code. And it looks like resizes should keep the file format.

Cool, it works in image field! :)

(Haha, never noticed that before. Somehow I did expect to get a JPG with any resize option. Mainly because of the typical "quality" option.)

I thought it didn't work too, but it turned out that my img-polaroid class had a background color. :-)
