Adding map to application (C# and JSON)

This application already has all the code written to it. But I think the county changed a parameter somewhere in the JSON code...so this might be just a bug find...and small rewrite. A coder described it as: "The program sends json query (lines 319-328 in [login to view URL]) that doesn't draw anything on the screen but it treats it as a success. This result is then treated as a picture and stored in a buffer. The "invalid parameter" you see is basically the program trying to convert this buffer into a picture and fails b/c it wasnt a picture in the first place. county maps are at [login to view URL] An example "TMS" number to input is "1361104008". When the mapping program finds this number, right click on the result and "zoom to". Here is the error message I am getting [login to view URL] Parameter is not valid. Parameter is not valid. Parameter is not valid. Parameter is not valid. Failed! parcel = 13611-04-008 The program does the following: a) at least 4 different scales of photos (i.e. zooming in and out on the property). These are available on the website: b) need to have the layer that shows the parcel outline on the satellite map c) need the maps named in the following convention [[parcel #][login to view URL]][1], where I will supply the application with a list of parcel numbers, "-01", "-02",...etc is the number to distinguish the different scales) d) maps available from: <[login to view URL]> e) use the same GUI and application structure as I currently have. f) If you are a qualified bidder, I will post the source code so you can look to see what it entails. I need a fast turnaround on this
