// First, we search though the text for all different kinds of media defined by media tags and store the results in $media_matches.
// Then the different replacements for the different media tags are stored in $media_replace.
// Lastly, we loop through all $media_matches / $media_replaces. (We choose $media_replace as index because $media_matches is multi-dimensioned.) It is important that for each $media_matches there is a $media_replace with the same index. For each media match we check the width/height, or we use the default value of 425x350. We then replace the height/width/media1/media2 parameter placeholders in $media_replace with the correct ones, before running a str_replace on $text, replacing the given media with its correct replacement.
