The addition of these two placeholders facilitates the inclusion and editing of images and hyperlinks in a signature. Although the current Signature preferences pane does offer the ability to insert a hyperlink, it’s not as obvious as it should be how to properly format it and editing it is even worse and very error prone. Although the solution that SignatureProfiler provides is not perfect, it seems better to me. I hope to improve it even more in the future.
In order to put a hyperlink or image link into the signature, you simply need to control-click (or right-click) in the signature pane where you want to insert the link. Note that sometime the editor is a little vague about selection when you control-click, so give it a try first to see how it behaves. The menu that you see looks like this:

The last two items in that menu are the ones that we’ll look at. When either is selected, you’ll get an sheet that looks like the one below. Note that the only difference will be that one has text for links and the other for images. The fields are essentially the same however.

The URL for the image or link indicates where to go an get the information. This should be a valid, reachable URL. No checking will be done at the time of entry to ensure that the link is valid. “Description” is the text that will be shown in the case of a hyperlink and is the descriptive text of an image. It is optional for an image.
After you hit the “Insert” button, the text that is entered into the signature looks less than friendly I must admit, but if you stick to editing just the link or description, you should be fine. Here is an example with both a link and an image inserted:

Another pointer for editing: if you want to change the formatting of a link, be sure to select the entire placeholder. Do not select part of the placeholder and apply formatting to it, this will break SignatureProfiler’s ability to find the placeholder properly.
Also, be aware that often Mail will not load the image correctly in the message compose window. You will see the standard icon indicating that an image cannot be loaded (
). However, the image will be seen by the recipient if they don’t have thier client set to not retrieve images. do a test by sending yourself a mail first. You will also notice that the preview of tail signatures in the SignatureProfiler preference pane doesn’t represent these properly. It is not yet capable of displaying HTML, that will come in a later version.
