[TODO: set image type on v3.0.9] PNG preview Thumbnail in backend not properly displayed for image field in item form was created by grabit

Hi,

When I use a transparent PNG as an image, the backend thumbnail is displayed on a black background and with a thick outline.

Backend here under

Frontend here under

Are you sure you saved the image as png and not gif? Also, if you save it you should use transparent background as option. It seems that you chose only one color to be transparent.

Hi Rooney,

It is a true png 24 bits created on photoshop. No gif not 1 color transparency...

Any ideas?

I had a look at the thumbnails generated by FlexiContent in my installation. If the original image has a transparent background the thumbnails have it also.
Perhaps Georgios can help.

Hello

the preview code uses phpThumb for thumbnail creation
and is not setting image type
- if type is not set then the default is JPEG

will fix by setting image type, here is a new issue for v3.0.9 (or maybe for v3.0.10)
