Passing bmp file/Image as parameter in wcf service

Question

I am trying to pass a BMP file as a parameter in a WCF Service. I'mm getting an error when the size of the BMP file is 350kb. When I pass a small file of 10-20 kb it runs perfectly.

The remote server returned an unexpected response: (413) Request Entity Too Large. 

[OperationContract]
byte[] ConvertData(Bitmap bmp);

I have tried to solve the issue with changing IIS setting following this link: http://blogs.msdn.com/b/jiruss/archive/2007/04/13/http-413-request-entity-too-large-can-t-upload-large-files-using-iis6.aspx but no luck

On your readerQuotas, try to set maxStringContentLength to 2147483647 as well, and make sure this config is set on both ends.

So both the server and the client need to have these values. It's no help if the client is allowed to send a large file, if the server will reject it anyway.

What is the value of maxArrayLength on the wcf server application
