Hey everyone, below is a script that I got online and have modified to be used for up to 5 images, instead of just 1. The script is supposed to take the uploaded file, resize it to 350px wide x (whatever heights end up), and also create a thumbnail that is 50x50px, then store into a database.
The script works great with everything except resizing the initial image to 350px. when using this by itself, the script worked great but now i cant figure out the resize for multiple images. if anyone could help me out it would be greatly appreciated.
Thanks in advance,
NickG
P.S. I’ve commented everything that needs to be looked at so you dont need to sieve through everything to find it.
