I am setting up a virtual squadron database. I want useres to be able to add their logo to there entry. So Imade it so that they type te URL and it use the <.image src="uRL here".> command in HTML

Is there any way to limit the size of the image or do I have to have them upload it...and if so how do I do that?

Or is tere any way to detect the image size...then resize it smaller maintaininng the smae aspect ratio?
Thanks,
Ryan

Are you having the users upload the file with a form? if so, you can use the following form, and you can set the max size the users may upload:

<form enctype="multipart/form-data" action="" method="post">
<input type="hidden" name="MAX_FILE_SIZE" value="15000">
<input name="uploaded" type="file">
<input type="submit" value="Upload">
</form>

You may use the getimagesize() function to get information about the image uploaded. It puts information into an array, and you can access different things. For example, say you did something liek this:
$image_size = getimagesize($image_file)

then ur width would be $image_size[0] and your height would be $image_size[1]. There is also other informatino stored in this array. You can find all the documentation on php.net. To change hte size, and maintain the aspect ratio, you could do something like this:

if ($image_size[0] > 350) {
$width = 350;
$height = (350 * $image_size[1])/$image_size[0];
} else {
$width = $image_size[0];
$height = $image_size[1];
}

This will resize any image that's wider than 350 px. Then you would do something liek this:

echo "<img src='image.gif' width=$width height=$height alt='' border='1'>

Hope this helps
