Sharing on facebook

Hi Karl

It seems the sharing on facebook on some pages doesn't "upload" the (preview) image.

It doesn't work with :

Home page : I've try with https://demo.photo.gallery/ and my website (I have set a preview image for the home page).
https://demo.photo.gallery/examples/features/post/
https://demo.photo.gallery/galleries/landscapes/ (maybe there's no preview image for this page)
https://demo.photo.gallery/galleries/human/ (maybe there's no preview image for this page)
https://demo.photo.gallery/galleries/
0344.jpg
0344.jpg (13.4 KiB) Viewed 3031 times
but it works with others pages :

https://demo.photo.gallery/galleries/nature/
0345.jpg
0345.jpg (31.23 KiB) Viewed 3031 times
https://demo.photo.gallery/galleries/femme/
...

Same for my website (even if I set a preview image)
for somes pages the image (preview image of the page) is shared
and for other pages the image is not shared

I don't know why


Thanks

This is just Facebook bugs again ... Check now, suddenly all the links you posted work again:

There are some bugs in Facebook. For a while, the Facebook debugger was reporting this:
Code
Provided og:image URL, https://demo.photo.gallery/render/w1280-h1280-q90/1.index/1.yosemite.jpg could not be downloaded because it exceeded the maximum allowed sized of 8Mb.
Clearly a mistake. That file is 212kb! It seems to have fixed itself ...

I found a fresh topic on the issue:

... as you can see the comments are similar to mine. Suddenly it fixes itself ...

Unfortunately, we can't do anything about issues with Facebook. Imagevue X3 presents an image, at maximum 1280px, reasonable file size ... You can try the facebook debugger for some of your pages. This seems to somehow rectify the problem, possibly after a short time period.
https://developers.facebook.com/tools/debug/sharing/

There are still minor annoyances with Facebook though. For new pages, it will sometimes show a blank image on first share-attempt. Why? Because I believe Facebook wants to show their share-page fast, before waiting for an image from the remote server. Mostly, if you close the share-window and try to re-share, the image is updated because it get's cached in their sharing-cache. However, the issue today I haven't seen before ... It's all Facebook glitches though, and nothing we can fix from our side.
