I use IIs (not IIS Express) and have link: OriginalString = "/Project/Global/Start%20page/slider_1.jpg"
Take a look at the ImageHelper.cs of MobilePack for an example on how to read the width: http://mobilepack.codeplex.com/SourceControl/latest#Head/EPiServer.Labs.MobilePack.Core/Helpers/ImageHelper.cs.
It looks like I found the problem:
but I can not give up windows integrated authentication.
Anyone else has solved this problem?
I have a link to an image (EPiServer.Url) stored into the global file. How do I get resolution for this image.
Thanks for any help.
