Hi olivtt,

Right now it is not possible 😢.
On ownCloud 6 the thumbails appear on the Web but the API where the mobile devices connect to interact with the sever does not have thumbails yet.
The idea is provide on the API a way to read the thumbails but I do not know when but I hope soon because it is something very useful and cool.

This would be very cool, lots of Android users want it too, see owncloud/android#317

FYI you can access image and file previews through the URL [server]/index.php/core/preview.png on the newest owncloud server release. It needs url parameters to tell it the image and dimensions and if you want aspect ratio preserved. The file path is relative to the webdav directory, so if you use the OCFileDto information you will have to strip off part of the path.
NSDictionary * parameters = @{@"file" : remotePath,
//@"a" : 1,
@"x" : @128,
@"y" : @128};
I have a PR open though I don't know if it will be accepted. The downloadPath api in OCWebDav needs to expose the parameters dictionary to outside control, which breaks the API. You can see the details here: owncloud/ios-library#64

Edit: Owncloud 7.0.3 has added an official API for thumbnails:

=> index.php/apps/files//api/v1/thumbnail/{x}/{y}/{file}

We will distinguish you different situations, either the files are downloaded to the device or not.
In this issue, we will include thumbnails just for those downloaded files.
NOTE:
From our experience with the Android app, it´s important to check extension such as tiff

This feature it is right now under QA process and will be within next release 3.4.7.

Hi, what about leave this issue open till release to app store?

[rperezb]

@jesmrec what do you think?

[jesmrec]

@TylerTemp the release is already done, that is an old conversation. Currently the iOS app supports thumbnails for both formats, regardless the pic is donwloaded or not.

We have opened an issue in core for thumbnails in servers with OAuth2 auth, it you want to track that problem or you are affected: owncloud/core#29914
