Images published through the API are showing up as white

[albattran]

Hey everyone,
Are there certain maximum specs for uploading images through the API besides the 1MB limit?
When I upload certain PNG files (less than 500K in size) they are showing up as a white canvas on bsky.app
The dimensions for the images are 4989x7639, I uploaded other images with similar dimensions and they work fine
Also if crop the faulty images by a certain amount they work (e.g. 4146x3505 works, but 4889x3524 doesn't work)

Any guidance if we should scale down images would be appreciated.
Thanks so much for your help!

Also here is a sample post with the PNG file showing up all white

This is unfortunately my first time jumping into it so I haven't tested other images yet, mostly just trying to get the one online before I take a shot at a larger project involving image posting. The latest one I tried to post was a scaled down version of the below image we also cross-posted to Tumblr.

So I guess it's not exactly apples to apples, sorry to pester.

I wonder if you may be running into a case similar to the one answered here: #1777

It seems similar in the way that it presents a blank image embed on the post, but I don't think it's being caused by the image dimensions. The images I've uploaded have been significantly smaller than what's included there. I'll run another test today with a different image and see if I can reproduce with different image sizes and dimensions.

This is an image I uploaded

{
    "blob": {
        "$type": "blob",
        "ref": {
            "$link": "bafkreifobhirsjz5ajnlnxcv3emxwrzqhbga4vuiwthk5ab6wr7v7zyjla"
        },
        "mimeType": "image/png",
        "size": 82487
    }
}

And this is what I sent to make this message:

                    "image": {

                        "ref": {

                        },
                        "mimeType": "image/png",
                        "size": 82487
                    }
                }
            ]
        }
    }
}

The issue might be something more obvious to someone else, but I'm not seeing it. Could very well just be in the structure of my json??

I'm facing the same issue of posts with images showing up blank, did you ever get a solution?
