Preview images are not shown when attaching images

[DavidMndz]

Describe the bug
When you are attaching an image into a Collective, it does not show the preview of the image in the select menu as it was before. It happens the same inserting from Files (Nextcloud) or from computer.

To Reproduce
Steps to reproduce the behavior:

1. Open a collective in Edit mode.
2. Insert an image from Files
3. Search for the picture you want to attach.
4. The previews are not shown.

Expected behavior
The preview of the image should be shown, otherwise it is very difficult to know the photo you select.

Dear @DavidMndz, thanks for your report. Can you please provide a screenshot of the problem? The dialog that's opened by "Upload from computer" is provided by your browser and not specific to Nextcloud. Unfortunately we cannot do anything about this dialog. But the "Insert from files" dialog is Nextcloud specific. I'd need a screenshot to better understand your problem though.

Hello @mejo- ,

thanks for checking the issue.

I was testing again and I can see the same issue with the files that I try to attach from my computer or from the Nextcloud files directly. I attach the screenshot from the option 'Attach from Nextcloud files'.

I hope this clarifies, if you need further details let me know please. Also, if you could please give it a try on your side to see if in your installation it happens the same, I think it could be useful.

Thanks again!

Now I see, you mean Nextclouds file picker. The file picker indeed changed recently in Nextcloud 27.1. Apparently the new version doesn't display previews any longer. This would need to get changed in nextcloud-libraries/dialogs.

This already got fixed upstream in nextcloud-libraries/nextcloud-dialogs#1015, but a new stable4 release of nextcloud-libraries/dialogs is needed.

Thank you very much for the assistance! I am glad it is already addresed and it is only a matter of time for getting the updated code through a new release.
