Please read https://drupal.org/node/1209090 and also follow the links to https://drupal.org/node/109994 and http://support.godaddy.com/groups/web-hosting/forum/topic/just-need-to-increase-the-max-upload-limit-via-php/.

For a start in php.ini or php5.ini (so php.ini5 might already be the wrong file name) the format of setting a php variable is not

php_value memory_limit 164M

as within htaccess but

memory_limit = 164M

If in doubt I would advice you to ask godaddy support to help you creating a suitable php.ini (or php5.ini).

@Ajay Did you tried upload the same image like custom file via Files? What's happens then?

Is there any plugin which I can use instead of "Tidypics" :-(
