Using images
Setting the default image folder for a column
You can choose an image for a cell in an image column by clicking the little image icon in the corner of the cell. Doing this sets the default folder of the column. However, lets say you don't want to go along and select an image manually for each column. There is a way you can do this in bulk - see below!
Setting the default image folder for multiple columns
If you right click a column header, down the bottom of the menu that pops up you can see the default image folder the column is using, and set the default folder for this column (and others) by clicking the 'change' button. In the Set image folder/s popup, you can click a folder and then click the 'Set image folder' button to make that be the default folder.
We would recommend setting it for 'All columns' in the project, assuming you've got all the images for your project in one folder.
Fun fact: Soon Dextrous will be updated so that all images belong to each project, so setting default folders won't be necessary anymore!
