An image annotator is a useful tool that allows users to edit and enhance images that have already been saved to their lab notebook. This can be helpful when trying to highlight or present particular findings that are significant. An image can also be downloaded with or without annotations after they have been made.
To start annotating images, an image must first be uploaded as an "Attachment" to a notebook. Once uploaded, hover over the image with your mouse. That will reveal the image toolbar that has 5 buttons.

Click on "Annotate" to open the annotator.
When you click on this button, your image will appear in a new tab with this toolbar above it (shown below):
Multiple functions are available when annotating, explained below.
This tool allows the user to draw freehand on the image.
This tool is used to create straight lines on the image.
This tool is used to create a circle and can be filled in or kept empty using the fill/opacity tool.
Similar to the circle tool, this is used to create squares and rectangles. It can also be filled in or kept empty using the fill/opacity tool.
The freehand shape tool is used to create freehand shapes that can be filled in or kept empty using the fill/opacity tool.
The arrow icon is used to move any items that have been added onto the image.
The eraser tool is used to remove any items that have been added to the image.
The text tool is used to add text anywhere needed on the image.
The rotate tools are used to rotate your image.
The clear sketch tool removes everything on the sketchpad.
The undo tool removes the last figure.
When adding a shape, the color or style of the shape can be chosen by using the format tool, shown above. The stroke color/width will affect the color and how bold a line will appear. The fill color/opacity will affect what color fills the shape and how clear it will appear.
When adding a straight line, an arrow can be added to the end by clicking the line button, or it can be set to a regular line, by pressing the arrow button. Both illustrated above.
