Dataform (plugin)

The allowed image types are defined in a lang string 'imagetypes' in the view's lang file as a pipe delimited list of types. The default definition is 'jpg|jpeg|gif|png|tif'. You can customize this string via Moodle ui or hack the lang file to add more types. For instance you you can change the string to 'jpg|jpeg|gif|png|tif|JPG' so that it allow JPG in addition to the other types. hth
