ico

So I'm making an application to store shortcuts to all the user's favorite applications, acting kind of like a hub. I can have support for actual files and I have a .lnk parser for shortcuts. I thought it would be pretty good for the application to support Internet shortcuts, too. This is what I'm doing: Suppose I'm trying to get Google's icon ( http://www.google.com/favicon.ico ). I start out by getting rid of the extra pages (e.g. www.google.com/anotherpage would become www.google.com . Then, I use ImageIO.read(java.net.URL) to get the Image. The problem is that ImageIO never returns an

I followed the The Qt Resource System guide and the .ico icons appear on Linux. The icons are not showing up on Windows when I try to run the applicaton from Qt Creator. I suspect a plugin issue based on Qt/C++: Icons not showing up when program is run under windows O.S but I failed to figure out what to do from the guide How to Create Qt Plugins . Is it a plugin issue or why aren't the icons showing up on Windows? If it is a plugin issue: How do I tell my applicaton where to find the qico.dll? Details of the environment: Works on: Kubuntu 12.04 LTS, Qt Creator 2.4.1 and Qt 4.7.4 (64 bit)

Is there a command line tool that can add an icon to an existing executable file? It should be able to set the icon as the file's "main" icon that is shown in Explorer. I don't have Visual Studio and cannot recompile the exe with custom resources containing the icon.

Resource Hacker is a free tool that allows you to modify resources in executables, and it can be scripted from the command line. Sorry, I haven't personally tried this one just yet, but because I am

This question already has an answer here: favicon.png vs favicon.ico - why should I use PNG instead of ICO? 8 answers In a HTML5 document, which favicon format do you recommend and why? I want it to be supported by IE7 and all the modern browsers. Also, when using .png, do I need to specify the type (type="image/png")? For compatibility with all browsers stick with .ico . .png is getting more and more support though as it is easier to create using multiple programs. for .ico <link rel="shortcut icon" href="http://example.com/myicon.ico" /> for .png, you need to specify the type <link rel="icon

Other than the fact that PNG is a more common image format, is there any technical reason to favor favicon.png vs. favicon.ico? I'm supporting modern browsers which all support PNG favorite icons. Amber Answer replaced (and turned Community Wiki) due to numerous updates and notes from various others in this thread: ICOs and PNGs both allow full alpha channel based transparency ICO allows for backwards compatibility to older browsers (e.g. IE6) PNG probably has broader tooling support for transparency, but you can find tools to create alpha-channel ICOs as well, such as the Dynamic Drive tool
