# Aliases

Aliases are a very easy way to hide parts of your URLs: They can be useful if your images come from different image repositories (for example: `https://static.mycompany.com/bucket/img`) and you do not wish these repositories to be publicly shown in your code. If you use only one repository for all your images, you can alternatively use [origin-url-prefix](https://docs.cloudimage.io/setup/shortening-urls/origin-url-prefix "mention").

With aliases, you can easily "mount" `src0` to `static.mycompany.com/bucket/img`*.*

## Step 1. Configure aliases <a href="#od_1e14582c" id="od_1e14582c"></a>

Log in to your Cloudimage admin console, navigate to *Image settings*, and scroll down to *Aliases*. Configure up to 10 aliases:

All aliases have to be prefixed *and* suffixed by underscores. Make sure there are *no* leading or trailing slashes. Please note that all aliases have to be unique for your account - aliases set in the alias section cannot be used in the Storage sections (see [connecting-storage-bucket](https://docs.cloudimage.io/setup/connecting-storage-bucket "mention")).

Due to the specific way aliases are matched, it is required to use only specific aliases that are *not* contained in part of other alias strings.

Example: If you define an alias `_demo_one_` then you should not have:

* `_demo_`
* `_demo_one_two_`
* `_my_demo_one_`

As those would all be matched according to the first overlap (in this example, `_demo_`). An easy way to overcome this is by both prefixing and suffixing aliases with double underscores.

## Step 2. Construct your  Cloudimage URLs <a href="#od_ea102014" id="od_ea102014"></a>
