Last week, I faced a problem to send an image to the server, I have tried a lot of ways, but seemed that nothing would work.

After some research, I found theHTTPClient API, this API helped me to do the dirty work, and it did pretty well. I will show you now, how to upload images and/or strings to the web server.

It’s pretty simple, actually. I gonna do in only one function!

3. privateBitmapbitmap;
5. //variabletosetanametotheimageintoSDcard;
