+## Creating a Tarball with Images
 
-A tarball is a collection of files and directories stored in a single file. In the context of `FastImageSequence`, you can use a tarball to store low-resolution preview images for your image sequence. This can be particularly useful when you want to seek or jump in the sequence quickly or when the internet speed is low.

In the context of `FastImageSequence`, you can use a tarball to store (low-resolution preview) images for your image sequence.

 To create a tarball with preview images, you can follow these steps:
 
-1. Prepare your preview images: Make sure all your preview images are in a single directory. The images should be in a sequence and named consistently (for example, `image1.jpg`, `image2.jpg`, `image3.jpg`, etc.).

 2. Create a tarball file. I have created an easy-to-use online tool for this: [Tar File Creator](https://reindernijhoff.net/tools/tar/) (no ads, login, etc). Drag and drop your selection of images onto the page, and a tarball will be generated that you can download.
