# Branding image requirements
To use the complete set of branded IFX, you need to upload nine image files. The nine variations are a combination of three sizes and three types of background. Although opaque versions of the images are not currently used, we recommend that you still provide suitable images in case new IFX are added to the library.
{% hint style="warning" %}
Each image that you upload must be less than 3 MB.
{% endhint %}
The required sizes are as follows:
* **Rectangle (landscape)**: 1024 px by 512 px
* **Square**: 1024 px by 1024 px
* **Portrait**: 512 px by 1024 px
For each size, the types of background are as follows:
* **Opaque**: Fill the background of the image with a solid color.
* **Transparent Light**: Use a light-colored version of your branding on a transparent background. This version of the image is used on IFX with a dark surface. Only PNG files support transparency.
* **Transparent Dark**: Use a dark-colored version of your branding on a transparent background. This version of the image is used on IFX with a light surface. Only PNG files support transparency.
