This code doesn't look like you seriously tried at all. You don't specify your modules, you set up variables you don't need, it makes little to no sense. It looks like a handful of cargo-culted lines from somewhere. On top of that, you want to figure out how to post something to a website? I suggest you spend a little time learning the basics of the language before trying to do this project.

In the event that you do know perl, then you sure chose a poor way of stripping down your code. You stripped out your use declarations, but you left in some lines that do *nothing* to further your task.

I hate to be bitchy, but It's a fundamental skill of debugging to be able to reduce your code to a small example to reproduce a bug. Another fundamental skill is to describe the problem. You can't send the image as raw data? Well, *what are the symptoms*? Blue smoke? A genie slapping your hand with a ruler? The Internet police issuing you a citation for "bad content uploading"?
