Add uploading via proxy

[cs-mshah]

I currently have to go through my college proxy to connect to the internet. This breaks the imgur upload as the proxy is not specified. Kindly make an option to specify proxy while uploading.
A better option would be to create an option to specify exact command line arguments too.

Hi @cs-mshah. What type of proxy do you use in college? Http, socks or something else?

Also, what did you mean by cmd line args?

Obsidian is an electron-based app. Electron has cmd-line args for setting proxy globally for the whole app. Could you please try this and tell me if it will work out?

We use Http proxy. I tried to launch obsidian using obsidian --proxy-server=address:port but the image still wasn't uploaded.

Ok. So, you can't upload without proxy.
I can add this feature.

What about displaying existing images? Do the get loaded with Obsidian in your college?

[cs-mshah]

Yes, existing images are visible, which means that Obsidian does respect the proxy, but it seems that while uploading to imgur, proxy isn't used.

I am surprised with such behavior. Are you sure they get loaded and not just cached from the times when you had a direct internet connection?
I am surprised, because I do not use anything special to upload images. It's just a regular fetch API provided by Chromium. If it respects proxy for loading images, why it does not respect it for uploading them? 🤔

So I got some surprising results:

• Some of the old images were not visible. I tried again after connecting with proxy and they seem to appear good as before.
• The upload also worked this time.

I feel that there is some issue of imgur with proxy, as I searched and found that several proxies block imgur. So if there are some domains that are free from the blocks then those could be used.
There doesn't seem to be an issue after all, but the results vary.

Can you support picgo core for upload? As I already have a tested configuration which works. All it requires is a command line argument and you can upload. It supports proxy too.

I think the reason you've seen some images behind proxy is that they were cached. Some old images you did not open for a long time were unable to load.

How did you specify the proxy settings for Obsidian?

The upload also worked this time.

Good to hear 👏

I think good VPN should work well too

Can you support picgo core for upload?

Looks like there is already a fork which supports PicGo: https://github.com/renmu123/obsidian-image-auto-upload-plugin
If PicGo is a self-hosted solution, then what is the benefit of it comparing to default pasting images to the vault directory?
