Editor button

Use the Image Tooltip button in the article editor toolbar. Choose image or text trigger, optional Joomla article ID (type it or click Select), Article load (plugin default, Inline, or AJAX), theme, placement, thumb path, thumb width, large preview, float, title, body, optional link, and link label, then insert.

If the button is missing:

• Enable Editor - Image Tooltip under System > Plugins
• Confirm your editor layout includes extra buttons (TinyMCE: Set 2 / Set 3, or the plugin list)
• Hard-refresh the administrator after install

The button writes a ready {itooltip} block. You can still add optional attributes such as fit="cover" in the source afterwards.
