I have recently switched from Windows to Linux (mint 18.2 with KDE, using Dolphin as file manager). I have noticed that when using the "open file" dialog (or upload file) in any external application you can't choose a remote url as source from the file

Remote file upload

In windows, if i paste an url as file source for file upload it gets uploaded just fine, here the "open" button is disabled (i know the image i typed does not exist but it's disabled even with an existing image)

Is there some way to do this on linux too? since i often upload images from the web into other websites this feature was very handy

  • I had this for a time in Ubuntu 16.04 Mate with Caja file manager, but it seems to have been sorted during some of the updates. I am now on 16.04.3 LTS and it is working as before. Maybe there are some updates which will take care of your problem.

    I have Dolphin loaded on my system. When I put a web-hosted image URL into Dolphin's address bar, I got an error line in Dolphin saying Dolphin does not support web pages, the web browser has been launched: Konqueror was then launched and the image appeared in it. This is not the same as your Open dialogue, but it suggests that your dialogue may work on current releases. My Dolphin release is 14.12.3 and Konqueror is 4.14.16.

  • What if you go into, for example, whatsapp or facebook and try uploading an image, when the open dialog appears then you press "CTRL + L" to open the location bar and paste an URL?

    When you put a URL into a file open dialog, Windows transparently downloads it into your profile as a "temporary internet file" and opens it from there. I have no answer for your question, but this info may be interesting to you.
