# Sample Images
Researchers and teams can add up to 5 GB of images per account. Each image has a maximum file size limit of 15 MB. Acceptable formats include, .jpeg, .png, .tiff, .bmp, .gif, and webpage url.
## Adding Sample Images
1. Navigate to 'Sample Images' under 'Samples' on the left hand panel.
2. Click 'Add Image' to add by either dropping images or 'Click to upload image'. You can also add an image by adding the URL link under 'Or Import File From URL'.
3. If the image is in the wrong file format or exceeds the maximum file limit, validation check will not allow the image to be uploaded.
4. Successful image upload will show up on the 'Sample Images' page and the 'Storage (for file uploads)' bar will update automatically to show how much storage you have.
5. You can update the image name and description by clicking the three dots and clicking 'Settings'. After updating the image metadata, click 'Save Changes'. You can also delete the image. This will unlink all your samples and permanently remove the image.
6. You can also link samples under the same dots by clicking 'Link Samples' and searching for the Sample Name or IGSN under 'Individual Selection'.\
You can also link images to a group of samples under the 'By Sample Group' and choosing your group. Click 'Linked Selected' (individual sample) or 'Link Group Sample' (for Sample Groups).
7. Another option to link images is by selecting 'View Resource' and clicking 'Link Samples' under 'Linked Samples'.
8. You can see your linked samples by minimizing the image using the arrow tab under the image.
9. On the same page, you can also remove links by selecting the sample and clicking 'Unlink Samples'. A popup notice will come up to confirm your choice.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.geosamples.org/for-researchers/register-samples/sample-images.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
