How to download images from VK using Url links?

Question

Qt

Using the QNetworkAccessManager Class , I can download images from the Google search feed that end in ".jpg" or ".png". However, when I try to download an image, the link to which is taken from VK, Telegram (I think the list does not end there), I inevitably stumble upon failures. The images just won't load. Probably, this is due to the peculiarities of the links themselves and they need a special approach.
As one option, I was advised to use curl in QT. Does anyone know if this will help? At the moment I'm trying to figure it out myself, but so far I'm getting only one error when I try to run the simplest code using curl.
