How to include image previews in Telegram bot responses?

I’m working on a PHP-based Telegram bot and I’m trying to figure out how to add image previews to my bot’s responses. Right now, I’m using the replyWithMessage method to send text replies. Here’s what my current code looks like:

$response = $this->replyWithMessage([
    'text' => $item['title'] . "\n\n" . $content
]);

This works fine for text, but I want to make my bot’s responses more visually appealing. Is there a way to include a small preview image before the text in the same message? I’ve looked through the Telegram Bot API docs, but I’m not sure which method would be best for this. Any help or code examples would be great. Thanks!

Absolutely! To include image previews with your text responses, you’ll want to use the sendPhoto method instead of replyWithMessage. Here’s how you can modify your code:

$response = $this->replyWithPhoto([
    'photo' => $imageUrl,
    'caption' => $item['title'] . "\n\n" . $content
]);

Replace $imageUrl with the URL of your preview image. The ‘caption’ parameter will contain your text, which appears below the image. This method allows you to send an image with accompanying text in a single message, creating a more visually engaging response for your users.

Just ensure your image URL is publicly accessible and the total caption length doesn’t exceed Telegram’s limit (typically around 1024 characters). If you need more text, you can always follow up with additional messages.

Hey there, I’ve actually implemented something similar in my Telegram bot. Instead of using sendPhoto, I found that sendMediaGroup works better for what you’re trying to do. It allows you to send multiple media files (including images) along with text in a single message.

Here’s a snippet that might help:

$response = $this->replyWithMediaGroup([
    [
        'type' => 'photo',
        'media' => $imageUrl,
        'caption' => $item['title'] . "\n\n" . $content,
    ]
]);

This approach gives you more flexibility. You can add multiple images if needed, and the text appears right alongside the image(s). It creates a nice, compact preview that users seem to prefer.

Just remember to keep an eye on your message size limits. Telegram has restrictions on file sizes and caption lengths. If you’re hitting those limits, you might need to split your content across multiple messages.
