FTP Downloading very slow in iPhone

Question

I am having an app in which I am using FTPHelper.h and FTPHelper.m files.

I am downloading the images from the dedicated server using FTP.

It works fine in my project but the images downloaded from server are very slow.

I have 50 images of 4.5mb to download and it takes almost 4 to 5 minutes to download.

I have imported two files FTPHelper.h and FTPHelper.m in my project and below is the code I am using.

-(void)getdata
{
    [FTPHelper sharedInstance].delegate = self;
    [FTPHelper sharedInstance].uname = BASE_USERNAME;
    [FTPHelper sharedInstance].pword = BASE_PASSWORD;
    [FTPHelper sharedInstance].urlString = BASE_URL;
   [FTPHelper list:BASE_URL];
    [FTPHelper download:file];
}

Is there any other way I can reduce the time for it?

Thanks...

Is there a way you can reduce the file size of these images on server? Since its 4 to 5 MB, most likey these are PNG files. Try saving them as JPG with 80% quality and you would reduce significant size. (This would be a lossy compression thought).

If FTP is not mandatory, there are alternates to downloading, Eg: use URL to access the image.(HTTP instead of FTP).
