Hi Paul, I hope all is well!

I tried that in LV 15 with the first PNG file I could Google, this:

The VI gives me error code 1181, source "DataSocket Read in Get File Data From Internet.vi->Download File from Internet.vi".

Could somebody upload the files "Download File from Internet", "Get File Data From Internet" and "Change File Extension" for LabVIEW 2013 please?

To download  a big file via http, you need to use the Range header keyword in the GET request, to partially download a file.
Example of header HTTP:

"Range: bytes=0-99"

to download the first 100 bytes

Take a look a complete example in the zip file.
