Hello  I would like to make restrictions to images in posts who are using "image" and html "img" tags. How to make preg_replace in markup so that if the image size iz larger than size[x] (width ONLY) , img tag gets width and height tags also (from config I guess). And maybe put the image in "a href" tag so that user can still click it to get the whole image on screen. Reason for this is that if picture is wider than your screen you have to scroll right to read posts. This is very annoying. Here is Astarans Restrict signatures to help.
Kind regards,
PaNTerSan

Also, Inline images might help - but this only works if image is attached.
Kind regards,

Hmm, I don't think it's even possible to do this because there's no way to obtain the width/height values if the image is being loaded via http.
It's easy to do with attachment images (and avatars) because those are loaded from the messageboard ftp using a defined path.

Hm - doesn't the client create a request for EVERY img tag?

Ok I researched the getimagesize() function, and it will work with URL's if using PHP 4.0.5 or higher http://ca3.php.net/getimagesize

I put together this code to be added in showflat & showthreaded, but strangely, it replaces the image(s) with nothing. Not sure what's wrong but here it is anyway in case someone else can figure it out... if ($config['allowimages']) {<br /> if (preg_match("/<img src=\"([^\>]*)\">/i",$Body,$matches)) {<br /> $image_new = $matches[1];<br /> $image_new = str_replace(' ','%20',$image_new);<br /> $max_width = $config['max_image_width'];<br /> $resize_width = $config['max_image_width'];<br /> $size = getimagesize("$image_new");<br /> $width= $size[0];<br /> $height= $size[1];<br /> if ($width>$max_width){ <br /> $new_width=$resize_width;<br /> $Body = preg_replace("/<img src=\"$image_new\">/i","<a href=\"$image_new\"><img src=\"$image_new\" border=\"1\" width=\"$new_width\"></a>",$Body); <br /> }else { <br /> $new_width=$width;<br /> $Body = preg_replace("/<img src=\"$image_new\">/i","<img src=\"$image_new\" border=\"0\" width=\"$new_width\">",$Body);<br /> }<br /> }<br /> } ...where $config['max_image_width'] is defined in config.inc.php
