RE: broadcast photo on other site not by up load
Season's greets, Eric fellow Perlites: Yes, chances are, if you're getting *something* but not an image, you're either sending the wrong headers to the browser OR you're sending the right headers and then getting a compilation error...Or both. On a windows machine, there's also the possibility that you're not using Binary mode on your image file handles (but since you're doing it in linux for the time being, that's one problem we won't have to worry about) What I usually do when this happens, is right click (from NS6+ or Mozilla) and do a view source on the image itself... in the source you'll see the actual output of your script which will contain the error, if there is one. Another good test, which I'm sure you've already done, is to makes sure that when you type % perl showphoto.pl you're script actually compiles, and runs and then spews a bunch of binary data to your terminal...(after printing Content-type: image/jpg\n\n (or whatever)) I'd recommend this over redirecting you're output into a file because it should tell you immediately if you're having compilation errors. The other thing to do is make sure you're dying where appropriate... I don't remember your original script but make sure you have things like: open(IMAGE,myPic.jpg) or die(Couldn't open pic! $!); (the $! will tell you what actual error occured... this way, if you've got the wrong path or insufficient priviladges, etc. you'll find out the easy way...

Compare it to other known good jpegs you have. Your showphoto.pl script should be able to read in a image and then print it out without corrupting it.

My suggestion is to work thru it step by step, until you see where the problem is. The first step is to get your script to output the image to it's STDOUT. In other words, you should be able to do showphoto.pl mytestout.jpg and you should get a good photo out. Then you want to put it in your cgi-bin and try to see where apache is messing up outputting the photo. It usually ends up being something very simple, which you are overlooking. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
