Use <img> tag but limit the size

Write code to use GD2 and pull out the width and height of the image in question. Then, you can rescale it if too big.

Where to modify this code is in the upload module. Look around this area:

      if (($file = file_check_upload('upload')) && user_access('upload files')) {
        global $user;

        $file = _upload_image($file);

        // ----- new code start --------------------
        $size = getimagesize($file);
        $width = $size[0];
        $height = $size[1];
        if ($width > 300 || $height > 300) {
             form_set_error('upload', t('%name: height or width too big', array('%name' => theme('placeholder', $file->filename))));
             break;
        }
        // -------- new code end -------------------

        $maxsize = variable_get("upload_maxsize_total", 0) * 1024 * 1024;
        $total_size = upload_count_size() + $filesize;
        $total_usersize = upload_count_size($user->uid) + $filesize;

        if ($maxsize && $total_size > $maxsize) {
          form_set_error('upload', t('Error attaching file %name: total file size exceeded', array('%name' => theme('placeholder', $file->filename))));
          break;
        }

Refer to the PHP Image functions. In particular getimagesize() which takes a file of most image extensions and returns back the width and height.

You could also add additional code to rescale it, but I'll leave that to you as an excercise. Let me know how it goes.

Note: the above wasn't tested, just a quick hack.

Take a look at the modules image and img assist.

Image allows uploading images as nodes, and features automatic resizing, whereas img_assist makes the entire workflow and addition of images to other nodes (stories) much easier.
