i created a qr code for a simple google form response url . and printed it as a image
Now can i change the url without changing the image because the image is laminated , is there any way to edit a existing qr code image without altering the image itself
Nope. The data is encoded in the image. In the future you could use a forwarding service (like tinyurl or goo.gl), they might enable you to edit the address it is forwarded to.
You can't change the url but you can put a html redirection on the actual destination page.

its not a programming question but really need it. I am creating a QR code that should redirect user to specific URL - let's say "http://facebook.com". Scanning all QR codes created by different creators I have used behave in such a way that it shows the URL and ask me if I want to open it. Can i force to open it in a browser without showing an URL like on the picture?
Okey, maybe someone will need it - you can't do it. It's all matter of app and most do like in the example - they let user decide if he or she wants to open this URL
Hi i am currently working in Asp.net using C# language.
Please any one tell me how to show picture that are stored server table(data type image) in asp:image control.
thanks.
You'll have to save the image in some folder on your website, and use a URL to link to that image. Since this is going to be done for every request, I'm guessing you can understand this is not a best practice.
The correct way to do this is save all images in a single directory on your website, and in the DB only store the URL for that image.
Does anyone know how to encrypt the following url holding values for phpThumb implemented in MODX so that it is stil readable to phpThumb extension?
As an example, the url for generated image looks like this:
/assets/components/gallery/connector.php?action=web/phpthumb&src=%2Fassets%2Fgallery%2F2%2Ftest.jpg&w=600
What I would like to achieve is to have this url encrypted so that a user would not be able to edit the image himself. Let's imagine applying watermark to an image using fltr, fltr would be part of the image url which if removed would remove watermark as well.
I have already looked into the Gallery Extra model and know where to look for the url constructor, yet I have no clue to which file the variables of the image url are passed to.
This means that I'm able to encrypt the image url but can't figure out where the decrypt function needs to be placed in order for phpThumb to read it correctly
By "user" I mean any site visitor without manager access.
Any ideas?
Might be a bit late but had the same issue...
Solved by using [[+image_absolute]] as placeholder for the img-tag so "src=[[+image_absolute]]"
I have a situation where I have to make a centralized image website. I want to secure those images from direct access. I want to send response with a watermark over it depending on request parameter. What is the best approach for it.
So far I have created a content website and directly accessing image.
Should I create handler from response.
But if I use handler will it be slow (response).
Kindly suggest me the best approach.
An image handler is the way to go, you will be able to check the http header referer and only serve image when appropriate.
There is an article on the code project that has all the parts you need:
http://www.codeproject.com/Articles/126421/Image-Handling-In-ASP-NET
You'll have to ignore certain sections and expand on others, but there is basically everything you need in the article.

Here, I created the handler for html and pdf types. You can implement the logic in same way for image.
I want to set up a zone in openx which will be invoked from a flash application, so I want openx to just serve back whatever xml I paste into the 'generic html banner'. Problem is when I use the invocation code for the zone, openx is putting some html around the xml i specified.
Is there a way to get openx to return the xml without adding html around it?
Edit: The same problem occurs no matter what zone type you enter, openx wraps some extra text around it. It appears what I want to achieve cannot currently be done with openx.
After investigating, I have found there is no out of the box way to get openx to return the xml entered without modification.
It might be possible using xml-rpc. However, if this is not a viable option, then you can consider creating a clone of the ajs.php file to only throw out banner content.
