I'm using Umbraco 8.1.5 and I've noticed that when I upload a PNG file to the media section, the thumbnail shows as a black tile in the list view, but when I click the asset itself to view more details I can see the image fine.
Then when I select the image to show on a page, it shows as black tile again.
Has anyone else had this issue and is this a bug or some config that needs tweaking for PNG support.
Are you running your site in Azure / using Azure Blob Storage for media?
yes, I am.
It's an issue with Image Processor with no known fix:
Sorry to not have better news.
Thanks for getting back to me. This is a real shame, guess I'll have to get the client to stick with JPGS instead and block the upload of PNGs.
Yeah, it's a bit of a nightmare tbh. We've had it on 4 sites now and it's just a pain especially when you want transparent images for things.
What's even stranger is that you'll find "some" pngs work but not all.
I'm seeing the issue with jpgs, strange enough but jpgs are displaying as a black box, any idea?
Are you using slimsy ?
like this furtherOptions:"&format=jpeg&bgcolor=fff")
Converting a png to jpg ? That if bgcolor not added will give black bars
I see the black box in the back office.
As you see an image shows as a black box in the media section. And it's happening only with jpg files
