Hello. What do you think about the ability for E-Blah to detect issues with the Human Verification Images?

My suggestion stems from a solved issue that I posted about in the support forum regarding the creation of Human Verification Images which contained a grid, but no text. The details of the fix have been posted there, but here I would like to expound on how to detect this issue.

The documentation on CPAN for the GD::SecurityImage module lists a method called gdbox_empty() which they suggest may be used in troubleshooting path issues (containing spaces, etc.). However, it appears as though gdbox_empty() can troubleshoot libgd errors as well.

gdbox_empty() must be called after create(). Line 164 of /forum/Code/Register.pl (v.10.2.5) is

Code $image->create(ttf,rect);

When troubleshooting, I made it the following

Code $ebout .= "\n\n<!-- Empty Image: \"$@\" -->\n\n" if( $image->gdbox_empty() );

That's not the cleanest way, but it allowed me to look for an HTML comment that contained any errors. Should you choose to catch this very non-frequent problem, I would suggest something like an e-mail or warning to the forum administrator. Maybe this can be tested during setup, or maybe it can be tested when enabling the option for Human Verification Images.

I will add it to my list.
