resized proportionately more images

Post by jacque99 »

Hello everyone
In fact, I have my script to resize an image proportionally works well and register myself with the image a name entered in a

text box on a

directory.

What I want changed is the ability to resize the same image three times (with the name entered in the textbox, and stored on the

server.
Thank you any indication which may help me to complete my script

Sorry, I'm having trouble understanding what you're trying to do. Might you clarify perhaps?

(Please surround your code with [syntax=php][/syntax] or [syntax=html][/syntax] tags appropriately.
