Imgur is very easy to use, you don't even need an account.
Here's a little tutorial as imgur can be used on a number of sites, not just the FeralHeart forums:
1. First, you'll want to go to the imgur site.
You can either do this by searching "imgur" on google or putting "imgur.com" in your browser.
2. You'll be then brought to a site that looks like this:
3. To post an image, click the "New Post" in the top left corner, right next to the imur logo.
4. Upon clicking "New Post" you'll be brought to a page that looks like this:
You have two options to post a photo, if you're wanting to post a photo from another site (such as DeviantArt stash, the FeralHeart forums, etc.) you'll pick "Paste Image or URL"
and posting a photo of your own from your computer (this is the most common option so this is the way I'll be teaching this tutorial). - "Choose Photo/Video"
5. You'll then be taken to a file explorer page, pretty self explanatory and I think this is something everyone can understand. Just choose a picture from your computer!
(for this tutorial I'm just using an image that I'll be posting here)
6. After choosing an image to post, you'll now be on this page. Congratulations, your post is successfully posted!
From this page you now have a link that you can use to host images on. To get this link, right click on the photo and click "Open image in new tab":
7. You will then be on a page that looks like this. The link is at the top of the page in your browser search bar:
8. With this link you can post images anywhere! To post images on the FeralHeart forums the code is:
[*img]LINK GOES HERE[/*img] (remove the asterisk and place the link in between, where the space is)
Please do note that image codes are different on sites depending on what code they useAnd that pretty much concludes the tutorial! I hope this helped in some way.
