Okay, I am going to put up a tutorial with things from start to finish, using Postimage.org, as it seems to be the easiest I could find, and it appears to be unlimited, and it resizes pictures to forum width for you.

Here's what it looks like when you get to their page:

picture hosting

Register and log in, then click upload a photo and alter the size to message board size like so:

upload images

It will tell you upload complete and give you this link table at the bottom, you want to copy the hotlink for forum one:


photo upload

You can do this either by hitting copy to clipboard, or highlighting and using right click to copy, or using crtrC.

Then you just paste in their link with either a right mouse click here, or a ctrlV:


upload picture

the upload picture underneath the pics takes you directly to their site to upload more, so in using this method, it will allow other people to learn how simple it is to do as well.

Hotlinking one of your own pictures from a picture sharing site like this is okay. Hotlinking a copywrite picture is not, nor is hotlinking a picture from another site like this:


(because I'm hotlinking from my own forum it's okay for illustration purposes)

When you hotlink to a non file sharing site, you use up bandwidth from that site, so if there is a picture that you own, and you want to share it, that is how you do it.

How you can hotlink from a site that allows you to do so and it's not copywrite, you do it like so:

Right click the image and chose copy image url.
click this button:

upload pictures

paste the url of the picture into the popup and viola, it's magically posted into the body of your comment! Beware that it might not be a very good size for a forum post, so you would do well to resize images if they are too large, by downloading them first and putting them through an imageshare site like postimage.org.

I also like servimg.com and even imgur.com for photosharing, the last one is super easy, but sometimes forums don't accept their pictures. Good luck and please, test below some photos using these methods!


ETA: RESIZING PICTURES VIA URL EDITS

This works for Imgur and Flickr, it might work for other photo hosts too.

You may add a letter to the URL, right before “.jpg”. The letter you add depends on the size you want.

s = Small Square (90×90)
b = Big Square (160×160)
t = Small Thumbnail (160×160)
m = Medium Thumbnail (320×320)
l = Large Thumbnail (640×640)
h = Huge Thumbnail (1024×1024)
