I'm new to fetching API responses and I'm trying to grab image data from a site called perchance.org. The output doesn't give me a straightforward API link; instead, it returns a long base64-encoded JPEG string. I'm able to see this base64 string in my browser's network tab, but I'm not sure how to capture and save the image it represents using any programming language. Does anyone have tips or code snippets for dealing with base64 strings?

Once you base64-decode the string, you'll have the image's binary data ready to save. This format is useful because it allows for binary content to be transferred through text-only protocols. I've even created a tool that might help: https://iamroot.tech/base64encode/. It's especially handy if you're working with several images at once!
Simply decode the base64 string using your preferred programming language. It should give you the binary image data directly, which you can then save to disk! If you're doing this often, consider using tools to streamline the process.
A base64 image string is just binary data encoded as text. To grab it, make sure you copy the full string from your network tab (avoid the truncated view) by using "Copy response." If you're programming in Python, you can decode it like this:
```python
import base64
img = base64.b64decode(base64_data.split(",")[1])
open("image.jpg", "wb").write(img)
```
This method works in any language, but you'll need to ensure you're copying the entire base64 string!
When you say "capture," I assume you mean saving the image as a file? If that's the case, you'll need to convert the base64 string back to its original byte form and then save it with a `.jpg` extension. Just let us know which programming language you're using, and we can help you find the right libraries or functions for this kind of encoding!
I'm looking for the code to actually capture and save the base64 results.
