I think you're a little confused about what you're trying to do.
If you wish to view the jpg image in your web-browser, you shouldn't open or print to the FILE file handle.
You also cannot print text and binary data at the same time.

If you just want to view the jpeg in the browser, change
print "Content-type: text/html\n\n";
to
print "Content-type: image/jpeg\n\n";
and then
print $newimage->jpeg;
Also don't print any text or anything else.

If you want to output a HTML page which contains an image, you must use the script to print out the HTML code, and in that code the IMAGE src href must point to a CGI which outputs only the image data (as above).

Hope this helps!
