How to grab the file properties of an online (image) file.

Recommended Posts

Hello to All. 

I'm trying to write a simple script that had a link of an image file (jpeg, gif, bmp etc) tell me some information [without having to download the file itself]

The info should be :

- urls file [my input]

- Width

- Height

- size


so I looked in the guide and in the examples what could help me, but I have some problems ...


I had thought of such a thing (not working):

#include <IE.au3> ; _IEBodyReadHTML ( ByRef $oObject ) ; X Internet Explore Browser
#include <MsgBoxConstants.au3>
#include <ColorConstantS.au3>;
#include <GUIConstantsEx.au3>;
#include <GuiEdit.au3>
#Include <Constants.au3>
#include <InetConstants.au3>
#include <Inet.au3>

Func InfoFileUrl ()

Local $sURL = "https://www.lastampa.it/image/contentid/policy:1.38524329:1582812892/puppy-looks-like-cat-dog-hybrid-14-5e53858271f0f__700.jpg" ;random test image taken on the web

Local $LinkOb = $sURL
Local $iWidth = _IEPropertyGet($LinkOb, "width")
Local $iHeight = _IEPropertyGet($LinkOb, "height")

;;------InetGetSize ( "URL" [, options = 0] )

local $size = InetGetSize ( $LinkOb , 0 ) ; https://www.autoitscript.com/autoit3/docs/functions/InetGetSize.htm
;; ------- FileGetSize ( "filename" ) ; https://www.autoitscript.com/autoit3/docs/functions/FileGetSize.htm
;only for files already on h.d, not for things online ?
;Local $size = FileGetSize ( $LinkOb )

ConsoleWrite ("Url File = " & $LinkOb & @CRLF & "Width = " & $iWidth & @CRLF & "Height = " & $iHeight & @CRLF & "Size File = " & $size )

EndFunc   ;==>InfoFileUrl


From other help posts on the forum I realized that the various _IE * etc * functions work on the Internet Explorer browser ... and I obviously ... use Chrome.    [ and maybe that's why I had this error message

<IE.au3 T3.0-2 Error from function _IEPropertyGet, $_IESTATUS_InvalidDataType> , or I have done something else wrong ?]



another user suggested the use of  inet*()


also, if you are only interested on the HTML source of a web page, you can simply use commands like InetGet(), InetRead(), _INetGetSource(). Such commands doesn't relies on any browser and can get the html listing directly from the web server.


I was interested in this solution because in the html code <img stile="......"> there should be Width & Height...

... I made some attempts but with no results.


Assuming that the starting idea is feasible, could someone please tell me what / how to correct ?

Maybe this ?

#include <IE.au3>

Local $sURL = "https://www.lastampa.it/image/contentid/policy:1.38524329:1582812892/puppy-looks-like-cat-dog-hybrid-14-5e53858271f0f__700.jpg"
Local $oIE = _IECreate ($sURL)

$cImg = _IETagNameGetCollection ($oIE, "img")
For $oImg in $cImg
  ConsoleWrite ($oImg.width & "/" & $oImg.height & @CRLF)

Thanks for the reply, I had not considered  <_IECreate >,  now I have set it as hidden.

I did some tests starting from your example and I still have some problems , 


#include <IE.au3>

;Local $sURL = "https://www.lastampa.it/image/contentid/policy:1.38524329:1582812892/puppy-looks-like-cat-dog-hybrid-14-5e53858271f0f__700.jpg";ok
;Local $sURL = "https://wdtqhni.bfhcyshosymc.hath.network/h/11395e61c41b4b59f6fff9dcd19701251adea614-44268-1280-1807-jpg/keystamp=1584999000-e70b55b7d9;fileindex=58597854;xres=1280/003.jpg"; no (1280x1807)
;Local $sURL = "https://www.ilpost.it/wp-content/uploads/2019/05/gatto-attento.gif"; OK
;Local $sURL = "https://mangadex.org/data/d7d595b12c597e93846d1975cf312afd/u6.png"; no (1000x4340)
Local $sURL = "https://mangadex.org/chapter/832015/6";no
;Local $sURL = " "

Local $oIE = _IECreate ($sURL, 0,0 ,1, 0)
$cImg = _IETagNameGetCollection ($oIE,"img")
For $oImg in $cImg
  ;ConsoleWrite ($oImg.width & "/" & $oImg.height & @CRLF)
  ConsoleWrite ("Url File = " & $sURL & @CRLF & "width = " & $oImg.width & @CRLF & "height = " & $oImg.height );


_IEQuit($oIE);Close the browser and remove the object reference to it


If I try to use some images, an window "view download" opens  (I think it' IE , never seen before ... as said, I haven't used IE for years) in which it tells me whether to open or save the file ( and the scrip end here ).

[ img of test =  h**ps://mangadex.org/data/d7d595b12c597e93846d1975cf312afd/u6.png ]

I also saw that with the presence of _IECreate now  <_IEPropertyGet>   seems to work , but



whit the image of previus test  the window " view download" open again ...

If i try to read the initial page of the image the retur is this

 Url File =

larghezza = 943
altezza = 647

but the real size of the immage  are 1000x4340 ;  ( so dont' work regularly)

Do I have to add something or is there any other approach I could follow? (for the size speech there are no viable roads?)
