i'm kinda new to this forum and consequently to ColdFusion itself so if i'm asking something stupid please forgive me. I'm trying to build a server side coded site and really liked cold fusion. It's great, i'm really doing well.
My questions is:
I heard that there is a way to upload a picture to the server, and it doesn't matter how big it is, it auto resizes the picture to the pre-defined size and pixels.
For example if i'm trying to upload a picture of 25mb 1000x1000pixels to the server, it automatically resizes it to the dimensions i have defined(for the sake of the example let's say 150x100px and 6kb size) and then uploads the picture. Also it auto-enters the name of the picture file to the database and outputs in a field the url name which directs to the file on the srver.
Does anybody know how this is done, and if there is a tutorial so we could learn it also.
Thank you in advance
You can fool some of the people for some time, and all people for some time, and some people for all time. You can't though fool all people, all time.

i've visited these sites but i can not find tutorials on how to do the actual script.
the only thing i can find is a ready program that does what i want, and i'm sure i won't be able to understand it.

It usesCFDev's AutoResize tag so you need to have it installed first. So do that first and then check back for a tut on how to make it work.
