hello,
I have written a code that allows me, through a form, to store info in the database + upload files on the server.
I would like to upgrade my script by storing on the server thumbnails of the images I can already upload.
I would like to make a variation in the name of the thumbnail too (not too hard...)
main image: 20071116_randomname.jpg
thumbnail: 20071116_thumb_randomname.jpg
BUT I have a problem with my code right now:
I am using a code that work like a charm as a standalone script: I use one image, that returns the thumbnail. but I have problems adapting this to my current script.
the thumbnail code return the path and filename in which i am working instead of the thumbnails themselves...
can anyone give me some clues on how i can handle that please?
thanks!

the idea is to store the thumbnails on the server with a variation in the name AND to store the thumbnails' path and name in the table (so I need to store the thumbnails' name in $thumb_array[])
hope someone can help me out 🙂
