/**
* Returns HTML code for an image element with form
* elements for uploading an image file.
*
* Uses the $id parameter as prefix for both the name and id attributes
* of all HTML elements. The names and respective suffixes are:
* - id+'_img' for the name and id of the <img> tag
* - id+'_src' for the name and id of the hidden <input> tag for the image path
* - id+'_type' for the name and id of the hidden <input> tag or <select>
* menu for the Imagetype
* - id+'_width' for the name and id of the hidden <input> tag for the width
* - id+'_height' for the name and id of the hidden <input> tag for the height
* - id+'_file' for the name and id of the file upload element
* The file upload element will provide the new image chosen by the user
* when the form is posted, while the hidden fields represent the previous
* state when the page was generated.
* The $path_default will replace the path of the image shown if that is
* empty, but the path posted back will remain empty so the default image
* is not accidentally stored.
* If the optional $imagetype_key is empty or not an array,
* no image type can be selected. If it's false, the image type field is
* omitted. If it's empty but not false, the current
* Image's type is used. If it's a string, the type is set to
* that value, overriding the Image's current type. If it's an array,
* the Image type can be selected from its values, and the current Image's
* key is preselected. The array keys *SHOULD* contain the Imagetype key,
* its values the Imagetype names in the current language.
* See {@see Image::updatePostImages()} and {@see Image::uploadAndStore()}
* for more information and examples.
* @param Image $objImage The image object
* @param string $id The base name for the elements IDs
* @param mixed $imagetype_key The optional Image type key or
* Imagetype array. Defaults to the
* empty string
* @param string $path_default The optional path of a default image.
* Defaults to the empty string
* @param boolean $replace_only If true, the image cannot be deleted,
* but there's always a file upload input
* to replace the current image.
* Defaults to false
* @return string The HTML code for all the elements
