# Manage Image Uploads (Angular)

When survey authors design a form or questionnaire, they can add images to use as a survey [logo](https://surveyjs.io/form-library/documentation/api-reference/survey-data-model#logo) or [background](https://surveyjs.io/form-library/documentation/api-reference/survey-data-model#backgroundImage), in the survey header, or within [Image](https://surveyjs.io/form-library/examples/questiontype-image/) and [Image Picker](https://surveyjs.io/form-library/examples/image-picker-question/) questions. Those images are embedded in the survey and theme JSON schemas as Base64 URLs. However, this technique increases the schema size. To avoid this, you can upload images to a server and save only image links in the JSON schemas, as shown in this demo.

To implement image upload, handle the [`onUploadFile`](https://surveyjs.io/survey-creator/documentation/api-reference/survey-creator#onUploadFile) event. Its `options.files` parameter stores the images you should send to your server. Once the server responds with an image link, call the `options.callback(status, imageLink)` method. Pass `"success"` as the `status` parameter and a link to the uploaded image as the `imageLink` parameter.

> In this demo, images are uploaded to SurveyJS servers from where they are then deleted after a predefined period of time. We strongly encourage you to use your own servers for image uploads when you use SurveyJS to collect sensitive respondent data in your application.
