Can I use a web location for the .Picture source on my Image control?

This is giving me some errors...

Code: 
Image1.Picture = LoadPicture("http://www.mywebsitehere.com/MyFolder/Test.jpg")

NOTE: This is just example text.. don't try to go to the link...

When did Power Query debut in Excel?
Although it was an add-in in Excel 2010 & Excel 2013, Power Query became a part of Excel in 2016, in Data, Get & Transform Data.

Try using a WebBrowser control and use the code below;

Code: 
WebBrowser1.Navigate "about:<html><body scroll='no'>[img]http://www.mrexcel.com/board2/images/newlogog.jpg[/img]</img></body></html>"

Excellent. Going to read up on more details on this "new" control. Help menu doesn't seem to be much help on this topic...

What follows is a modification from

Put the following in a standard module:

now, you can call this function like

<font face=Courier New>
<SPAN style="color:#00007F">Private</SPAN> <SPAN style="color:#00007F">Sub</SPAN> Command1_Click()
   <SPAN style="color:#00007F">Dim</SPAN> Url <SPAN style="color:#00007F">As</SPAN> <SPAN style="color:#00007F">String</SPAN>
   Url = "http://www.mrexcel.com/board2/images/avatars/1739339495404fef2bc2773.gif"
   Image1.Picture = LoadPictureUrl(Url)
<SPAN style="color:#00007F">End</SPAN> <SPAN style="color:#00007F">Sub</SPAN>
</FONT>
