Circuit Diagram is a free, open source application which enables you to make electronic circuit diagrams and export them as images.

The new user interface should make designing circuits much easier.

Components are now displayed in the new toolbox on the left hand side, with icons rather than text to tell you which component the buttons represent (a popup also lets you know which is which when you hover over one of the images). Clicking on one of the items in the toolbox allows you to place that type of component (or move/resize a component if the select tool is used).

Please note that if not all of the components can be displayed in the toolbox at once, a scroll bar will be shown. This can be disabled by going to Tools->Options and disabling "Show toolbox scroll bar". You can still use the mouse wheel to scroll through the components.

In addition to clicking on the items, holding the mouse button down over one which has a small triangle in the bottom right hand corner causes it to expand and reveal additional similar components which can be placed instead.
