Is there a way to insert a JS code or something that would basically restrict all videos/images that are posted to a specific size?I.e.- 480w 250h. I don't necessarily need this done for me but if anyone knows as to where I can find a tut on it or instructions on how to do so that would be amazing. I want to implement this into my n13 so people who post wont "blow out" the site bounds. Plus I think the images/videos look better at this size.

Okay i just saw the include that resizes the IMAGE, however I still haven't found anything that will allow me to resize a video. Please help.

Not possible for the script to resize videos unfortunately. Some javascript could probably do the job but then again it might just be easier to manually resize the video via the code before posting it.
