I've tried to help people add images to posts before and thought, maybe, a more detailed guide would be useful. Maybe Admin could make this a sticky?

First, please read Admin's post about posting images at https://forum.forest-of-dean.net/index.php?id=53194

It's not possible to upload images directly to the forum. To post an image in this forum, the image has to be hosted on another server somewhere and then a link to it is posted in the forum. This is known as hotlinking. There are several image hosting services but not all allow hotlinking. To be able to post the image into the forum a link to THE IMAGE is required but not all image hosts provide this. Many only provide a link to the page where the image can be viewed but not the image itself. If you're unsure, look at the end of the link for the image name extension (such as .jpg or .png or .gif etc.). If there is no image name extension, then the link is not to the image, only the page. Here's an example.

Link to an image:
https://i.imgur.com/vGfkokz.jpg

Link to the page where this image is displayed:
https://imgur.com/vGfkokz

Two image hosts that allow hotlinking are Flickr (www.flickr.com) and Imgur (www.imgur.com). Both work but I personally use Imgur as I find it's easier for this type of use so thats the one I'm going to use here.

For the image to be displayed in the forum, not only do you need the link to it, but you have to tell the forum software that it is a link to an image so the software knows what to do with it. This is done by wrapping the link in a BBcode like this:

[img]https://i.imgur.com/vGfkokzt.jpg[/img]

Note the [img] and [/img] tags at the begining and end of the link. This is the BBcode for an image. For more information about BBcodes, look here https://www.bbcode.org/.

So how do we do this. Again, I'm using Imgur as the host. Using other hosts will be similar.

First, I recommend creating an account on Imgur. You don't have to. It's possible to store images on Imgur without an account but, if you don't save a link to it you'll never get back to it. Whereas, with an account you get a page that shows all your uploaded images and you can go back to them at any time to create links, edit or delete them. You also get more options when creating the links to the images such as resizing the image. How you create the link you need depends on whether you have an account or not so I'll do it both ways. First, if you don't have an account.

Go to www.imgur.com. Click on the New Post button in the top left of the screen (of course, this may be somewhere else if Imgur decide to update their layout in the future). You will get a screen that says Drop Images Here. Find the image on your computer using File Explorer (on a Windows PC) or whatever file manager software you use. Drag the image you want to upload to the Imgur screen. The image will be uploaded and displayed on the screen. Put the mouse over the image and you will get two buttons appear in the top right. Click the '...' button.

A menu will appear, click on Get Share Links.

A dialog with some link options will apear.

The easiest option here is to click the BBcode Link. This will save the link, with the BBcode tags added, to your clipboard. You can then paste this link directly into your forum message without having to use the Image option in the forum the purpose of which is to add the BBcode tags.

Now if you have an Imgur account.

Go to your Imgur images page and drag and drop the image you want to upload onto the page. It will be uploaded and a thumbnail of the image will appear. CLick on the thumbnail and the image will open with a number of link options by the side.

The easiest option, as before, is to click on the BBcode link but, before doing that, note the optons below it that allow you to specify the size of the image. You should experiment to find which size is best by choosing one, copying the link and then pasting it into your forum message then use the forum message preview option to see how it looks. If it's too small or too large, go back and change the size and copy the link from Imgur again.

There is another option here which can be useful if you have an image that needs to be large to be read but is too large to be displayed in the forum. Below the BBcode link option there is a Linked BBcode option. This will create a link that will display the image and also provide a link back to the original on Imgur. Using this you can post a small image in the forum which anyone could click on to then view the larger version on Imgur. There is one caveat with this method and that is, because of the way the forum is displayed, it will try and open the image within the forum and this won't work so anyone wanting to view the larger image will need to open it in a new tab.

Try it with this example. Right click on the image and select 'open in new tab'.

(Note: for some reason Imgur thinks my example horse picture may be an 'adult' image so you may need to confirm you're over 18 to view it...).

Hopefully this is clear enough but if you reply to this post with any questions, I'll try to help further.
