-### Passing images to Pixtral
+### Passing images to the vision model
 
 1. **Image URLs**: If the image is available online, you can just include the image URL in your request as demonstrated above. This approach is simple and does not require any encoding.
 2. **Base64 encoded**: image Base64 encoding is a standard way to transform binary data, like images, into a text format, making it easier to transmit over the internet.
 
-To encode Base64 images in Python, you first need to install `Pillow` library:
-
-```bash
-pip install pillow
-```

 ## Frequently Asked Questions
 
 #### Is there a limit to the size of each image?
-The only limitation is in context window (1 token for each 16x16 pixel).
+The only limitation are the tokens context window and the maximum resolution supported by the model (images will be automatically downscaled to fit within maximum resolution). Refer to our [model catalog](/managed-inference/reference-content/model-catalog/#mistral-small-31-24b-instruct-2503) for more information about supported formats and token dimensions for each model.
 
 #### What is the maximum amount of images per conversation?
 Each conversation can handle up to 12 images (per request). Attempting to add a 13th image will result in a 400 Bad Request error.
