When you refresh the page, is the duplicated image still there?

Hmm interesting, so that means the image is duplicated physically. So before uploading the file to the server, the web will check for this format

web-{file_name}-{last_modified_date_in_utc}

If the file is modified or has different names, then it will upload.

Can you help me check the file? Modified can be seen as moving a file from one location to another

i think i have understand the problem... i have made a first upload of this pictures. The date/time of file was wrong, so i made a quick program for extract OrginalDatetime from the metadata and re-apply it to files before re-uploading (as there is no deletion for now).

It was my assumption your where calculating an hash of file for testing if picture was truly unique. (i use this nuget in .Net CoenM.ImageSharp.ImageHash, for calculating hash in a personal program using image....).

PS : For french translation, i will make a pr when #246 will be merged :)

Regarding the jpg.jpg extension: It seems to me that images uploaded from the web create a double .jpg extensions and the images uploaded from the app creates a single

This can be a solution, related to the deduplication on the server.

@SirBogner This might be a bug. Do you have a way to reproduce? If so, would you mind open an issue? I will take a look at it

When i have the webview open and upload images via iOS, i see duplicates in the web view. When I download them, the files have different IDs. After a page refresh i don't see duplicates any longer.

V 1.13.0
