Posting images in the Lithium software is a bit different than it was in previous HC software. Here's how it's done. First of all, either create a new topic, or reply to an existing one.
A Post Message box opens up, with the Rich Text tab selected as the default. Immediately below the rich text tab you'll find a line with an assortment of tools and icons, including B (bold text) I (italic), U (underscore), strikethrough, the icon for the spoiler tag, Insert Code icon, Paste from Word icon, insert emoticon icon, insert link icon, insert image icon, insert video icon, and two list icons for ordered and unordered list. The insert image icon has a graphic image of a little tree on it. (Fig 1) To insert an image the steps are fairly straightforward, but differ slightly, depending on whether your image resides on your local computer, or is online in an image hosting site such as Photobucket. Let's look at each separately.
Figure 1: Click on the "tree" icon to insert images into your post
If the image is on your computer, first click on the image icon (the little "tree"). In the dialog box that opens up, click on "browse." This opens up a box that allows you to browse your local computer. Once you've located the image file you want to upload, click on it to select it, then click "open." Alternatively, you can double-click on the file name in the browser and open it automatically. (Fig 2)

The file name will automatically be inserted as the Image Title, but you can change it and give it a different title if you want. You can also select the size that the image will display, as well as its alignment - the default Inline, or left or right. (Fig 3)

If the image you wish to post is located on another site, click on the image icon (the "tree"), then click on "From another site." A box opens up. Insert the URL for the image you wish to hotlink to. Unlike with vBulletin, it's not necessary to insert [img][/img] tags - just the "direct link" URL. (Fig 4) In fact, if you include IMG tags, you'll get an error message. Once you've inserted the direct link URL, a "Load Image" box appears. Click on that to load the image. With images from other sites, you'll also need to title the image before you can insert it into your post.

Once you've made your selections (or if you're okay with the default settings and image title), simply click on Insert Image and the image will be inserted into your post. You can then continue adding additional text to your message, additional images, videos, or whatever else you want. Once you're finished, click the blue Post button (located directly below the rich text dialog box) and your message and image will be posted.
Do you have an image that you like and want to use fairly frequently? The software has a feature that allows you to quickly re-post a previously uploaded image. Click on the add image icon (the "tree"), and when the dialog box opens up, select the "From My Uploaded Images" tab. This opens up a list of all your previously uploaded images. Simply locate the one you want to post, and double-click on it to select it. As before, you can select the image display size (Image Size) as well as the Image Alignment. Once you're satisfied with your choices, click on the blue Insert Image button and you're done. (Fig 5)
