Avoid hotlinking with imgur
I know I'm way late to the party on this one, but I just discovered a very useful site called imgur
Most people, when they want to post an image in the forum, just hot-link. That means you put a direct link to the image on whatever site you found it form. For example, to post a Penny Arcade comic, they will do <img src="http://www.penny-arcade.com..
This is a bad idea for many reasons. The biggest reason is that there is no guarantee the image will still be there forever. Eventually your post will have a broken image in it, or the hoster of the image will block you. One solution is to post the image in Flickr, Photobucket, etc. and link to that. This sometimes works, but depending on the site, they might cut you off. Also, who wants random silly images clogging up your Flickr which is supposed to be your personal photographs?
I would often just upload images to the server which runs these forums by hand. However, this is a pain in the ass.
Thus, we come to imgur. They gladly host and serve any image that you either upload or link to. Then link to the imgur version of the image from the forum, and it will work forever. It's probably a bad idea to put all the eggs in one basket, but users at big sites like reddit are using imgur. If they go down, other sites will have the same big problem that we do.
I encourage you all to use imgur when posting images in this forum. If you have a site that provides the same service, please suggest that also. I'm considering maybe doing something to the forum to automatically imgur any images that are linked and are not already imgur'd. What do you think?
Also, if you go to the tools section of the imgur site, they have browser extensions and such and such.
