Tascus projects give a way of organising folder locations that production sequences use.
Create a new Project with the following steps:
This will open up a window where you can create a project name, then specify the media directory and the results directory for that Project.
When you are editing a sequence, the Project name is shown just below the Sequence Name in the top right of the sequence editor window.
Now, when you browse for an image in Display Work Instruction, it will start in the Project Media Directory. All relative paths for images in the sequence will begin with the Project Media Directory.
