Obtaining Image File Dimensions From URL - excel

Question

I have this link:
https://s23527.pcdn.co/wp-content/uploads/2017/04/wine_speedlights_kit_lens.jpg.optimal.jpg
It is on Cell A2:
I want to get on Cell B2 the dimensions of the URL of this JPG
(I don't mind how to get it, it can be 1920 on cell B2 and 1080 on cell C2)

Answer 1

You will need to make an API call to URLDownloadToFile to download your image. In the below example, we will download to the temp folder C:\Temp\.
Once your image is downloaded, you will create a new Shell object, and ultimately use the .ExtendedProperty() property to grab your file dimensions
After you have finished downloading your file, you can go ahead and delete the temporary file using Kill().
The below method uses Early Binding. You will need to set a reference to
Microsoft Shell Controls And Automation
By going to Tools -> References in the VBE menu
Option Explicit
#If VBA7 Then
Declare PtrSafe Function URLDownloadToFile Lib "urlmon" Alias "URLDownloadToFileA" _
(ByVal pCaller As Long, ByVal szURL As String, ByVal szFileName As String, _
ByVal dwReserved As Long, ByVal lpfnCB As Long) As Long
#Else
Declare Function URLDownloadToFile Lib "urlmon" Alias "URLDownloadToFileA" _
(ByVal pCaller As Long, ByVal szURL As String, ByVal szFileName As String, _
ByVal dwReserved As Long, ByVal lpfnCB As Long) As Long
#End If
Sub test()
Const tmpDir$ = "C:\Temp\"
Const tmpFile$ = "tmpPicFile.jpg"
Debug.Print URLDownloadToFile(0, ActiveSheet.Range("A2").Value, tmpDir & tmpFile, 0, 0)
ActiveSheet.Range("B2").Value = getFileDimensions(tmpDir, tmpFile)
Kill tmpDir & tmpFile
End Sub
Private Function getFileDimensions(filePath$, fileName$) As String
With New Shell32.Shell
With .Namespace(filePath).ParseName(fileName)
getFileDimensions = .ExtendedProperty("Dimensions")
End With
End With
End Function
