v5.0.6

in http://b2evolution.net/news/2013/09/17/your-feedback-matters I suggested that for a future release b2evolution should accommodate specifying custom image size for inline images. This way the user can specify inline image size individually instead of it being all the same...

Below is the function found in [_item.class.php] which I customized to accommodate this function.

When the user insert the image it normally inserts when there is no $title specified. With a title specified it inserts
, however, with the added lines of code the user can customize the inline image size by adding ":fit-400x320" or ":fit-520x390" or what ever sizes ($thumbnail_sizes) are available in _advanced.php. eg

the lines of code added:
[codeblock lang=php line=1]

// CHANGED regular expression to accommodate image size
[image:(\d+)(:?)([^\]preg_match_all( '/\|\:]*)(:?)([^\]]*)\]/i', $content, $images );

if( !empty( $images[0] ) )
{ // There are image inline tags in the content
foreach( $images[0] as $i => $current_link_tag )
{
$current_link_ID = (int)$images[1][$i];
$current_link_caption = empty( $images[2][$i] ) ? '#' : $images[3][$i];

// ADDED START

$current_link_ID = (int)$images[1][$i];
if( empty( $images[3][$i] )) $images[3][$i] = '#';
if( empty( $images[5][$i] )) $images[5][$i] = '#';
$current_link_caption = empty( $images[2][$i] ) ? '#' : $images[3][$i];
$current_image_size = empty( $images[4][$i] ) ? '#' : $images[5][$i];

if($current_image_size !== '#' )
{ // see if the image size specified exist in $thumbnail_sizes

load_funcs( 'files/model/_image.funcs.php' );

if( in_array($current_image_size, get_available_thumb_sizes()) )
{// the size specified is ok,, use it.

$params['image_size'] = $current_image_size;

}
}

// ADDED END

// ... rest of code ect...

here is the complete function render_inline_images( $content, $params = array() ) after changed:
