WHere can I find some C source that will allow me to read a jpeg image rotate it and write it out? OR a plug-in that will allow a jpeg image to be rotated on a web page?
THanks in advance..

Your best bet here is Java. Java 1.1 has built-in functions for cropping, streching and rotating gif and jpg and if the functions are made public, JavaScript can control it.

well, depending on your specific preferences...couldn't you just have another image that was the same image just sideways?

Understanding Web Applications

Without even knowing it, most of us are using web applications on a daily basis. Gmail and Yahoo email, Twitter, Facebook, and eBay are used by most of us daily—and they are web applications. We often confuse these web applications tools for websites.  So, what is the difference?

Sorry to reject your answer sasidhar. I have been all over the web searching for some source.

Michel,
 You hit the nail on the head for me. I need a java applet that can rotate a jpeg. Repost your comment for the points.  

Thanks to both of you for the reponces...

michel, Thanks I would greatly appreciate the code. I have been torn BTW writing some C code (which I still want to do  ) to read a jpeg file and rotate it or as you suggested to use a java applet and go that route. SirCaleb - you are correct in your statement. That is what I was what I was going to do with the C code. I was going to read in the image file rotate it and redisplay it. I just have not found any C code to facilitate that yet. Hopefully the applet code will do what I am wanting to do .
Thanks again...
