Image Bam is a website that offers 'fast, free image hosting'. When I was considering destinations to write about for people that were looking to share photos online, it came to my attention that this place has quite a reputation for speed. I did a few tests and can say with confidence that out of the big names out there, this location definitely has a few tricks up its sleeve.
One of the biggest advantages to Image Bam is the fact that you can upload files via zips, meaning that multiple photos is not an issue in the slightest. I tested the speed and found that it capped my upload too - not bad for a place that I only found out about while researching.
Image Bam supports images up to 10 MB in size and also has a few photo management tools with functionality to add titles and descriptions. It's all free too, so if you're worried about paying, you don't have to.
