problem with WWW url & question mark

I had 4 Jpeg cameras with links:

when u paste it on browser, it will show 4 cameras, but when I worked with WWW class, it just showed only first camera, I guessed the problem is question mark. will anybody help me figure it out?

I got it, thank you all for answering me

The problem is I need to add key & value with WWWForm to php link has question mask in the JPEGStream.cs, look like this

form = new WWWForm();

form.AddField(“ch”, 0);

or form.AddField(“ch”, 1);
