But this is static everytime we see the some.jpg. The advantage of using php to return image is that you can provide a authentication validation, i.e, the user must have signed in to view the image. Thus automatically hot linking is prevented. (Hot linking is the use of images of other servers, by another server. for eg an image on www.example.com displyed on www ...

Resolve Net::MySQL Hang problem if the database result has only 1 row or is empty

http://digitalpbk.com/perl/solve-netmysql-hang-problem-if-database-result-has-only-1-row-or-empty . If the result set is having just one row MySQL returns FE 00 00 02 00.
