OT: selling on ebay

Never had that before, despite using ublock origin. Once you've uploaded, can you go in to edit the photos on the ebay site (crop, etc) - do they stay the solid colour or do you get the images back?

Try a different browser? The 'random colour' thing on other websites can be due to generating a 'preview' of an image that's only one pixel high, that gets expanded to the full frame. Something may have gone wrong in the CSS/etc.

I tend to upload photos from the mobile app because it's quicker if you've taken them with the phone: I create the listing on the mobile app, add the images, save as draft, and then go to the computer to edit it.

I do find that once you have completed the listing on the computer and pressed the preview button at the bottom (the one next to the 'list now' button) the listing appears as it would but the image gallery doesn't work, so you can only see the first image but not scroll through them. When you do the actual listing the images work, and you can go back and edit the listing if something isn't right.

I applied for my bus pass on-line and uploaded a photo. The web page gave a preview - it was my whole face but with such a poor resolution it looked as crime watch had doctored it to make me anonymous. Luckily when the credit card size pass arrived it had a fairly high resolution photo. :)

You need to upload from the app. I have never managed to upload a photo from the laptop.

It's a problem with the photo. Taking a high-resolution photo (JPEG) and editing it with Irfanview does *exactly* the same thing for me. Taking a lower-resolution photo and then just uploading it 1:1 unedited works.

I haven't been able to figure out just what in the edit process triggers the pastel block: there's the EXIF tags or their lack, rotation marker, diverse JPEG features (lossless rotation, for example), etc. It may have something to do with the JPEG/GIF quality setting; ISTR lower worked; don't know if that's a size issue or not. Some websites also respond to a large high-resolution photo with an error message which does *not" say "file too big", but that then turns out to be the problem.

Thanks I'm back home now, so will try it again tonight after scaling the image down ...

I'd try to use a "quality" setting well under 80 first -- I couldn't quite figure out which of the settings I tried were the important ones...

I tried loading into GIMP and crop very slightly saving with 94% quality remove EXIF rescale to 50% size convert jpeg to png

none of which made any difference

using chrome instead of firefox worked (an unfortunate trend of many websites)

Just try uploading the original photo to ebay directly? The ebay picture editor will do all those edits, and I find the workflow quicker than repeated File->Open, File->Save As in an external editor.

(unless you strip EXIF it'll share the EXIF with ebay, but I think they re-encode everything for their purposes with no EXIF so the punters won't see it)

Not had problems with Firefox myself, although not tried Windows.

When I do that, the initial thumbnail is rendered correctly, but then it uploads in the background and the whole image becomes a random pastel colour.

But I'm editing the pastel image ...

Why not run the "file" command on it (Linux or WSL) and see if there is a unique property inside it.

I was working with what I thought was a text file the other day, and grep would not finish scanning my text file. When I saw the output of "file", I knew I was sadly mistaken about my assumptions of text. And there appeared to be some binary corruption in the file, like some clusters didn't get written at some point. Once I edited out all the binary blunders with a hex editor, grep began working again.

You've probably taken the picture with an Apple product :-)

Another possibility is some kind of "automatic classifier" on the website, has rejected the picture. For any number of reasons.

"You may include pictures, as long as they don't infringe third-party rights and they follow our policies, including the Feedback misuse policy, the Offensive materials policy, the Adult items policy, and the Illegal explicit content policy."

ISTR that quality well below 94% did the trick -- 75% or so.

Been a while: now I just scale back the number of pixels when taking the photo for ebay.

Latest example is my pension provider website now gives me an endless stream of zebra-crossings and motorbikes to identify, thankfully I can get past by solving the audio version.

original file from phone

jug1_a.jpg: JPEG image data, JFIF standard 1.01, aspect ratio, density 1x1, segment length 16, Exif Standard: [TIFF image data, little-endian, direntries=11, manufacturer=Google, model=Pixel 5a, orientation=upper-left, xresolution=164, yresolution=172, resolutionunit=2, software=HDR+ 1.0.611900660zd, datetime=2024:04:07

50% resize, 95% quality, EXIF stripped

jug1_a - Copy.jpg: JPEG image data, JFIF standard 1.01, resolution (DPI), density 300x300, segment length 16, progressive, precision 8,

Same but as PNG

jug1_a - Copy.png: PNG image data, 1450 x 1512, 8-bit/color RGB, non-interlaced

The only Apple product I wanted was an Apple ][, from the EXIF, you'll see it's a Pixel5a

Multiple images of stoneware chemists jars?

I read the Wiki on JFIF and can't see anything there that is an issue. No evidence of a non-standard pixel setup (appears to be RGB24). Your edits did a nice job of "cleaning" the smelly bits of the original file.

I could not find any mention of "segment length 16" and what the significance of that is. I have a number of JPG pictures here that don't have that field.

My conclusion is that it's firefox, I can try later with a clean profile, but I did already try with ublock and ghostery disabled.

try the edge browser within the Sandbox app within Windows 10/11?

It does work with Chrome, so I'd be surprised it it didn't work with Edge.

I think Firefox vs Chrome is reaching the same point that Netscape vs InternetExplorer got to, i.e very few websites bother testing with FF now :-(

Someone else had the same problem -- and no solution:

"I upload my photos and ebay transforms the photos into blobs of solid colour for some reason. The photos are .jpeg, less than 1MB each, less than 1600 x 1600 and greater than

and, no, no helpful suggestions.

To make an exception for sites you WANT to be able to do that, after the problem occurs, look for a new icon next to the lock icon in the address bar. It should look a bit like a picture. Click that to manage the permission related to this feature. "

I have 'privacy.resistFingerprinting' turned off and ebay works. I turn it on and I upload a stripey picture, if I turn it off and upload the same picture I get the correct image.
