Resizing image uploads
Sorry I'm quite sure other have asked this question before, but the threads I've looked through have added to my confusion, rather than sorted it out, so I'm hoping someone can give me some instruction.
I'm using photoPost 5.1. Right now I am putting a limit on the photo file sizes (350 kb) my users can upload. This has started to cause problems because users don't know how to resize images to smaller sizes. But I don't want to allow them to upload giant-sized photos that will fill our hard drives. I believe reading the threads that I can allow users to upload any sized photo, and then have GD take that photo resize it down to the specifications I would like, such as no wider than 600, no taller than 900, but I want to make sure that I'm not opening the server up to huge file uploads by doing so. I only want a thumbnail, and a large photo, I don't want to keep the original large image at all! and I don't want a medium sized version either. Could anyone tell me the proper upload settings I question below? thanks a million!
Thumbnail image max width and height in pixels: 100
Max allowable image width in pixels: 600
Max allowable image height in pixels: 800

If photo upload width or height exceeds maximums, resize upload down to max dimensions: yes
