Restrict thumbnail image size?

[Radical3]

in the backend you set set the thumbnail image size however, when a user uploads a thumbnail for an image and its too large, 4images still accepts it?

is there a way to restrict size , or resize thumbnails on upload??

basically where can i go to force all thumbnails to one size?

SOLVED MY OWN PROBLEM

FOR PEOPLE USING 4IMAGES AS A VIDEO SITE,  THIS IS CRUCIAL. LET PEOPLE UPLOAD THE VIDEOS AND THE THUMBNAILS
THEN USE CSS TO RESIZE THE THUMBNAILS, EASY.

files to be edited
templates/{yourtemplate}/thumbnail_bit.html
templates/{yourtemplate}/random_image.html ----- if you still use the random image
templates/{yourtemplate}/style.css

BACKUP YOUR STUFF

open up thumbnail_bit  and look for

Code: [Select]

{thumbnail}
Now wrap it in div tags like this

Code: [Select]

<div>{thumbnail}</div>
give the div an id of anything you want, im gonna call this "resize"

Code: [Select]

<div id="resize">{thumbnail}</div>
go to random_image.html and look for {thumbnail} then place it in the same div id as before

Code: [Select]

<div id="resize">{thumbnail}</div>
save and close the files, now go to style.css and add this at the bottom

Code: [Select]

#resize {
height:135px;
overflow: hidden;
width: 135px;

}#resize img {
height:135px;
overflow: hidden;
width: 135px;
max-height:135px;
max-width:135;
}


change your height and width change it to whatever you use.
max-height, max-width(the last two lines of css are crucial) this is the part that does the resize.

ive tested this in :
firefox
safari
opera
IE6
works perfectly, 

WARNING: this hack will not resize porportionally, it is not gd2 or imagemagick , its only css, it will resize every thumbnail you have, BUT NOT PERMANENTLY.
