I'm writing an image conversion web service. the idea is that the client can either:

A) send up an image to be converted to a different format and then sent back
B) request an image held on the webservies server, which is then sent down to the client in the requested format.

Both of these functionality work, but not for big files.

If i try A) with a 16.5mb tif then i get the following exception



code:--------------------------------------------------------------------------------

I've done a quick google and one suggestion i've seen is to alter the request limit in the web service. but i'm not sure what to change it to?

Well you basically need to set it to a value for the maximum image size you wish to allow someone to try and use. You need to take in consideration who is going to be using the service and what kind of connections they will have as well as expected traffic. You don't want to overload you connection but you also don't want the client to wait 30 minutes for the image to upload.

Other than that its pretty much a judgement call on your part.
I wouldn't recommend anything voer 10 megs personally.
