I guess Ramiro just wants to know the dimensions of the image data so he can resize it correctly, like 30% smaller or something like this. Since I assumed that he wanted to resize the images like this, he needed to get an actual file and then use getimagesize() on it. After he gets the dimensions and do his proper calculations, he can use <img width="boo" height="boo"> to resize the image, while still using the same binary data from the database. That's why I told him it was a dirty hack. I guess I didn't explain myself very well on that one, but oh well :) Regards, Joao -- Joao Prado Maia Web Developer Kefta.com, Inc
