# Customizing the Image Map

### Adding custom tags

The default labeling vocabulary contains about 1200 terms that are
frequently used to tag photographic images. To add additional custom
terms, click on the Settings icon. You can then add up to 500
supplementary terms that will be applied to clusters and individual
images. It may take up to a minute for tags to update after this
operation.

### Changing the cluster strength

The clustering algorithm uses a cluster strength coefficient to
control the size and number of identified clusters. Higher
coefficients lead to larger and fewer unclustered images. By default,
InvokeAI tries to balance the coefficient so that not more than 10% of
the images are unclustered. Usually this is good enough, but if you
wish to adjust the cluster strength manually, you can do so by opening
up the Image Map Settings dialogue, and adjusting the "Clustering
Strength" parameter. Make small incremental changes. If the value is
too high, most of your images will coalesce into a single monster
cluster. If the value is too low, most of your images will be
unclustered singletons. The Image Map displays these in gray.
