image-uploading

问题 I'm working in a project that doesn't use much of the .net framework and instead work with Request.Form posts.

问题 I am trying out Jquery File Upload from blueimp. The documentation says I should be able to limit the number of files to be uploaded with the maxNumberOfFiles setting. However, that doesn't seem to be working in my case. None of the others such as acceptFileTypes, loadImageMaxFileSize etc seem to be working either (probably I have to include other js files? - don't know really which ones or how to hook em up despite researching quite a lot) .
