Wanted order: ASP Chinese character verification code source code

In fact, the Chinese character verification code has no other benefits besides causing trouble for people...

In fact, if the verification code is creative, it can be made very cute...

My previous space verification was like this...

Generate a random number C between 1 and 4...

If it is 1 Or 2... Then two numbers from 1 to 100 are generated...

The larger one is A and the smaller one is B...

If C is 1 verification code That is to enter the value of A+B... It is 2 and enter the value of A-B...

If C is 3 or 4... two numbers from 1 to 10 will be generated...

p>

If it is 3, the user needs to calculate the value of A*B...

If it is 4, the user needs to calculate the value of (A*B) / B...

I think this is very cute...

After seeing my verification code, my friend thought of a cuter one...

She has pictures of small fruits. .. About a dozen pictures...

Use GD to process a row of seven or eight random pictures...

The verification content is... How many pictures are there in the picture? An orange...
