I believe.. then you should create a real images from those blobs.. use this tutorial to create those images:

Create files with php

there.. this blob will be this $content.. so replace it..

and then.. after your script ends.. just delete those images.. then just use

PHP Code:

unlink(); 


but..when you're creating a name for your file.. use

PHP Code:

uniqid(); 


then when you have lot's of users it won't delete someone else image

i believe it works
