Will an image I uploaded still show if I deleted it from my computer file?

Yep, the image will still show because you UPLOAD it. if you LINK something to fanpop and the original is removed (true for links (duh!) but also for videos)thats when you wont be able to see it on here anymore once the original is removed.
and because the image is uploaded to fanpop its so important to credit where you got the picture because there is no way of knowing the source!

its also important to use good keywords..but thats just a sidenote :P
