"Insert Existing Attachment" - from where?

[Ace in Space]

Alright, so this isn't exactly an intro, as I've made a handful of posts elsewhere, but this is still a "I'm new to the forums and can't figure out how to work this website" question, so I figured it belonged here. When inserting pictures in a forum post you have the option to "Insert existing attachment" or use an image from a URL.

Of course, I have no existing attachments. But the fact that such an option exists implies there's a way to upload attachments. But I can't for the life of me figure out how to do that. Which is rather sad, considering that it's hardly rocket science.

Can somebody tell me how it's done?

Attachments came with the forum software, but are turned off here because it would cost Squad more to pay their server host to store attachments and pictures. Instead, upload your files and screenshots to file sharing sites, and then use the links they provide in your forum posts.

Ah, thank you! That makes sense.

Imgur is the best one, but if you don't want to (or can't) use it you can use others like Google Photos or even Photobucket (which isn't free, like it used to be). 

And just a quick tip, if you have questions or need help doing stuff on the forum, you should put your topic in the 'Kerbal Network' section
