It’s just more convenient that way. No need to synchronize data between database and disk storage.

But really, some noobs don’t even know how to store resources anywhere other than database.

In term of performance, storing images on disk is always the best choice.

Well I started with storing to disk use fwrite etc, but after writing a captcha program I really got interested in using header data to output images.

I have never really done a benchmark to compare MySQL image output to Disk output but since technically when using SQL the data must be read twice (Once to read the SQL database and again to read the Image data)

It is also more RAM intensive it seems.
