i have a few png files in my asp.net 3.5 web app. the images displaying correctly in dev; however, when i load the app on the server, the png files do not display. i'm using w2k8 and iis. when i server another image file from same directory (jpg), it works. is there something i am missing with png files?
This sounds like a permissions problem. Have you checked the permissions on one of the PNG files to be certain that they can be read by EVERYONE?
If you can access the server directly, can you see the images if you use a browser on the server and visit the local site? http://localhost/
Can you try view the PNG directly by URL from your browser? By that I mean entering the full URL to the PNG itself rather than the page that is showing the PNG. For example http://sstatic.net/so/img/logo.png
Very late but maybe not a wrong solution:
If you rename a .jpg to .png it won't show in Microsoft's browsers.
If you save the file again in Paint for example, it will change the mime-type or file-headers thus it will load after that change.
You can test this pretty easily:
Rename a .jpg file to .png
Load the page : The image is broken
Save the file as .png now
Load the page : The image will load now

I'm trying to see if it's possible to extract font & svg data from an archived flash website
Is this possible?
Note: I am using this extension on my chrome to run flash website
Screenshot of flash website
Solution:
Download the .sfw that contains font or vector file. If the fonts are not embedded in SWF, it will not work.
Open the .swf with Action Script Viewer to extract .ttf
There might be a simple answer to this but I have not found it.
I'm trying to get an svg file stored in an Azure blob store to download to the browser.
The corresponding png downloads to the downloads area of the browser.
If I do the same for an svg it opens the file by default in a new tab.
The following for the png works as wished for.
Png
The following for the svg opens a new tab and displays the svg rather than downloading to the
downloads of the browser.

Is there a way of overriding the browser behaviour for svg files or is there a simple jquery
type solution for this?
Yes there is.
You need to change content-disposition of svg file in blob storage to attachment
If this does not work you can also change Content-type to application/octet-stream
Probably right now you have content type image/svg+xml
Using the latest online version from VSTS.
Is it somehow possible to use vector graphics in the vsts wiki?
I know I can't upload a .svg as attachment (only png, jpeg and gif) but is there any other approach?
In the end, it is just static file serving. Using markdown, I can use any url to a public .svg and the image gets rendered correctly using the VSTS wiki. But I can't upload the graphic on my own. Also it has to be uploaded inside VSTS, a public file hosting location is not allowed.
My Idea was to upload the vector graphic inside the code section and inside the wiki to reference to the corresponding .svg. But I cannot or simply don't know how to get the full url to the .svg.
Any hints for that?
You can use the markdown for image syntax () to show vector graphics on wiki page (but the xml format hass not been supported yet).
While to get the url for a local .svg file, you need to hosted .svg file to a place with http protocol supported. But it seems there has no free site to hosted .svg files. And you can also refer the post free and convenient svg hosting.
I would like to create a shockwave file that can display a website with an internal webbrowser or something similar. The final target to display the website in a pdf file, but I think the only way to do this, is the swf trick.
I tried to find resources for this on the web, but found nothing.
UPDATE:
I am looking for a way to display a website in a downloadable pdf file. The website is only one html file fuelled by jquery and css.
Download SWF template for your website and edit it in macro media flash editor.
I would use a PHP script to create a PDF file (my choice for this kind of stuff is TcPDF, which has many example/how to scripts ready to use), and I'd put a captured image of my website in it; there are several websites offering this service for free, just google it, for example webthumbnail.org.
Disclaimer: I'm not linked to TcPDF nor Webthumbnail.org in any way, they are just the first examples that came into my mind.
Sometimes when you view a file on a page on its own, the browser has some default way of viewing it, like to place it in an image or video tag, or invoke some plugin. Other times, it just downloads the file.
Sometimes this is because of headers set by the server, but lets ignore that for now. For some file types, it doesn't matter what headers were set -- the browser will try to download them regardless.
Some of the types that the browser will view are listed in navigator.mimeTypes. However, this is not authoritative. The iPad can view Microsoft Office files but it does not report this.
Is there any simple way to figure out what the browser is going to do with a file before it does it?
