# Add public links

Beside uploading files to **Data**Gym.ai, public links can be used. The button "Add public links" opens a new input form to list all urls.

![List here one or more public available urls.](/files/-M-FEVLOe8g598YtvFjq)

{% hint style="info" %}
Do not forget the **https** part of the url.
{% endhint %}

{% hint style="warning" %}
External image are not downloaded from **Data**Gym.ai. This feature should only be used to import images from your own resources. Otherwise, they may be moved or deleted from their owner and they will no longer be available through their link. 
{% endhint %}

The uploaded images appear in the images list with the image type "**SHAREABLE\_LINK**".

If something went wrong, a error dialogue is displayed. All uploaded links can be found there sorted by their error type. Just toggle them to see all.

![](/files/-M-FKE0Kw1yMKw8MQr8J)

{% hint style="info" %}
The external storage may be limited by your subscription plan.
{% endhint %}

There are also errors with external images that can occur at a later time. For example, when a linked image is not available anymore because it was deleted from your server. **Data**Gym.ai will detect these kind of errors, when you or your team members try to annotate or view these images in the label mode.

If an image is not reachable anymore or has an invalid data format, the corresponding task will be skipped. The specific image will be marked as invalid in your dataset's image list. Please occasionally check your image list to verify that all your images are valid.
