+</code>
+This snippet defines a function called `dolarpagano` that accepts two arguments: `update` and `context`, which are provided by the `python-telegram-bot` library to handle updates and message context in Telegram.
+Within the function:
+  - It gets the current date and time using `datetime.now()`.
+  - The date and time are formatted as a string in the 'ddmmYYYY_HHMM' format using the `strftime()` method, where 'dd' represents the day, 'mm' the month, 'YYYY' the year, 'HH' the hour, and 'MM' the minutes.
+  - A URL is constructed using this formatted string to include the updated version of the image resource. This is achieved by concatenating the base URL string with a query parameter `v` carrying the updated timestamp.
+  - Finally, it responds to the Telegram message with the generated URL using the `reply_text()` method of the `update.message` object.
+In summary, this function generates a URL pointing to the latest image of a dollar meme and sends it as a reply to a message in Telegram with the 'v' parameter to bypass Telegram's thumbnail cache.
