# Generate a slideshow from AI-filtered images

In this day of mass storage on all our devices, it can be difficult and time-consuming to go through and filter all our images. In this demo, we aim to negate this annoyance by automatically detecting what objects are present in an image and creating a slideshow from the wanted images.

[🤖/image/describe](/docs/robots/file-filter.md) allows you to easily detect objects within a image. It can return a list of discovered objects as a text or JSON file, but in this demo we're passing the list to [🤖/file/filter](/docs/robots/file-filter.md) so it can filter our images which do not include flowers.

Using [🤖/image/resize](/docs/robots/image-resize.md) we can take all of our selected images from the previous step and resize them to the same dimensions. From here we pass those images to[🤖/video/merge](/docs/robots/video-merge.md) to generate a slideshow. To create a slide show simply label all images as `image` using the `as` key, similarly, if you want to add a backing track, as we have done using [🤖/http/import](/docs/robots/http-import.md), simply label which audio file you want to use as `audio` using the `as` key.

Step 1

### Handle uploads

We can handle uploads of your users directly. [Learn more ›](/services/handling-uploads.md)

## So many ways to integrate

Transloadit is a service for companies with developers. And there are many ways developers can put Transloadit to good use inside your company to automate media processing.

#### Bulk imports

Add one of our [import Robots](/services/file-importing.md) to acquire and transcode massive media libraries.

#### Handling uploads

We are *the* experts at reliably [handling uploads](/services/handling-uploads.md). We wrote the [protocol⁠](https://tus.io/) for it.

#### Front-end integration

We integrate with web browsers via our next-gen file uploader [Uppy⁠](https://uppy.io/docs/guides/uppy-transloadit/) and SDKs for Android and iOS.

#### Back-end integration

Send us batch jobs in any server language using one of our [SDKs](/docs/sdks.md) or directly interfacing with our [REST API](/docs/api.md).

#### Pingbacks

Configure a [notify\_url](/services/content-delivery.md) to let your server receive transcoding results JSON in the `transloadit` POST field.

#### On-demand

Use our [Smart CDN](/services/file-importing.md) to adapt files on-demand and stream them directly to your users.
