So, let’s suppose you have a form where a user can upload an image, and you have to scale it and save it into your database. One single code line, solve-me after 3 hours of blind search! Here is a function to resize an image and maintain aspect ratio. It will resize jpeg, gif or png and could easily be modified to add bmp.
100 is the quality settings, values range from 0-100. Regarding Carl Gieringer’s comment, it is possible to have PHP files in utf-8.

Here is the simple, but powerful script for creating thumbnails on the fly. This resizer respects the ASPECT RATIO. I had a problem with denied permissions when trying to upload AND resize an image having safe_mode on. Note: the directory where you want to save the file must have permissions set to 0777.

This simple code will increment from 1 to 3 on images. This script will call a script to produce the image. This script creates a square image and places the text on it. I had similar problem with safe mode. JPEG as a filled form, but printing both Graphics from Photoshop revealed that any JPEG created is downsampled to 72 dpi, while width and height is kept.
