I don't normally post this kind of thing, but I found a really cool tool for uploading big files on my pages.
I'm always looking to keep the load light on my free hosting here to keep things moving smoothly, but needed a way for people to send me big files.
After some digging, I found http://www.sendthisfile.com/
They have a great little upload tool that embeds directly into your site so you can integrate it in your pages and save the load on your own server. Big time saver when clients need to send me big image files and need an easy solution that keeps them on my site.
The basic service is free and can do files up to 2GB. They have paid options too, but the basic one is good enough for what I need. It has a small advert on it, but a little CSS trickery can fix that. (Not that I ever would)
Enjoy it while it lasts!!
