How to download image, FTP using any one send sample code.
Please search the forum a bit, this question has already come several times. You can use QFtp for that, there's both a Qt 4 and Qt 5 version.
To add to SGaist 's repsonse.
QFtp is supported only in Qt 4. There are some implementations available for using QFtp support also in Qt 5. However, this is for support of Qt 4 implementations in Qt5.
For Qt 5 it is better to use directly QNetworkAccessManager.
Instead of using an HTTP url to a file, use an FTP url.
