First thing you do is this. Right or left Click (depending how you have it setup) on the picture you want to use and select COPY Image URL.
If you already have the image url from uploading it somewhere, then great. We can use that.
Now Click here The little pic that looks like a Mountain with a moon or something in the background.
When you do, a box will popup asking for the link. Just paste the link in there and click OK.
Next you highlight the WHOLE LINK of the picture you want to hyperlink to a thread or external URL.
Select the little box picture of the world with the infinity sign.
When you click on it, a popup box will appear prompting you for the link. Copy and paste the link you want and click OK.
You see this here. The IMG is still highlighted and when I clicked OK it wrapped the URL around the whole IMG
Shows that here. Now I selected the whole text for the hyperlinked image.
For the most part you are done. If you are in your SIG Editing area.
To get to your Signature Area go to Control Panel. Thats on the top left of the screen. Or go to http://www.tacomaworld.com/forum/usercp.php
On the left hand side of the screen you have the EDIT SIGNATURE - It is under the Settings & Options
Now you are brought up to the screen that would like this without all the stuff I have in my sig.
If you just want to hyperlink TEXT for example "BUILD"
All you do is select the text
Now select the world again.
And input the link you want there.
See the Build is still highlighted with all the additional linking around it. At this point you could change it to BOLD By clicking the B or change the color by clicking the "A" with the black bar under it.
It will look like this now. All the hyperlinked data and words.
When you finally post or click save - either an actual Post or your sig that is, it will look like this and will be clickable.
