Alt Tags for Images

You can use the advanced HTML output for that. I’ve added a new tag. Update to 2.2.

Now switch to advanced view, go to “Advanced” tab, mark the checkbox “Use custom HTML output” and in the “Custom HTML output box” input the following:

<p>
{$stickers_start}
	<a href="{$sticker_url}" target="_blank"> <img src="{$sticker_img_url}" width="32" height="32" alt="{$sticker_name}" /></a> 
{$stickers_end}
</p>

For any other customization check the “Other notes” section here which includes the documentation.

Cheers.
