IE Save Image as

10 posts in this topic

#1 ·  Posted (edited)

Greetings all!

I want to open a web page and then save one of the images on that web page on my hard drive, just like we would do manually, by right clicking on the image and then choosing the "Save Image as"

Since the image is the result of a dynamic img src URL, and for other security reasons too, I can't download the image directly from its img src URL. The web page MUST be opened on the browser and only after that, the image can be saved locally. This the reason I need to mimic the "Save Image as" stuff.

Is there any ways of doing that without using the coordinates and the mouse movement features?

I'm trying the path below, but I'm stuck at this since I couldn't find more information to achieve my target.

#include <IE.au3>
$oIE = _IECreate ("http://www.autoitscript.com/")
$oImg = _IEImgGetCollection ($oIE, 5)

Thanks in advance.

It's not easy. I made it and posted it in the German forum, but AM, the Server is renewed, so I can't get it. :D

I thought that after getting the handle for the image, I just would need some more instructions to mimic the save image as...

Do you have the link to the forum that you said so I can search there later? Also, tell me some keywords that I should use on the search to find your mentioned posted.

Thanks!

I believe you are looking for the InetGet Funtion.

:D

it would be helpful for analysis if you post the original URL

The original URL is not available for you guys since it is an intranet system that uses user/password for login. Only after the successful login I can plot the graphics that I need to download. And the graphics are not a direct link to an image, the img src code point to an asp script, not the real image. Then, the image displayed on the screen is the result of this asp script that runs on the server. So I can tell you for sure that it is not possible to play with the HTML code on it and neither download the image directly without opening the page and getting the image from the page itself. If you try to download the image directly using its img src url, you will not download anything else than a blank picture. This behavior happens for security purposes of the intranet site.

I hope I don't need to go deeper on why I must download the image using the IE "save picture as". Trust me, I must use this, but I'd like to avoid mouse moves and clicks to minimize the chance of fail.

Thanks!

:D

The inetget would not work since it would open a new session to the server, and I must use the same browser session that I used to login to the system. If I use the inetget I would download a wrong and invalid picture.

Thanks anyway.

Anybody else knows how to mimic the save picture as?

The DOM does not give you the ability to programatically save files for security reasons.

I don't know of another way to do this other than mouse clicks.

If you are not awre of it, _IEPropertyGet will allow you to get the screen coordinates of an element, like an image, however... but you'll still need to simulate mouse clicks.

Thanks Dale, but in this case I will prefer other path, to simulate hot keys on Firefox. In Firefox, with Send("^s"), I can easily save the entire page (with images) and then grab the images that I need from my local hard drive.

The only thing remaining to make it work on Firefox, is to detect if the page has been already loaded in Firefox. Do you know how to do that?

Thanks!
