One of the problems has been that the sending limit for district email is small, as well as the attachment limit. Also, sending large files via email is clunky and slow, and not very reliable. Fortunately, I found a solution that's been tested to work, and I want to share this with the schools I service.
http://drop.io (100MB limit for each drop)
Please BOOKMARK this site for easy access. Here are the steps:
1. Click "Select Files." Go to where the pictures are located. If you have MULTIPLE pictures, you can hold Ctrl on your keyboard and use your mouse to select the ones you want to send.
Special Note: If you are sending a lot of pictures that are in separate folders as albums, it's best to FIRST name your folders, and ZIP them: right click the folder and choose "add to zip". Then you simply send that ONE ZIP folder as one file, and do that for EACH album folder,
2. Click "Create a Drop." Wait for the files to upload; this could take a while depending on the size of the files and the speed of your network.
3. Copy the link at the top of your browser. Paste that into an email and send it to me. YOU DO NOT HAVE TO ENTER AN EMAIL ADDRESS ON THE WEBSITE. That's simply if you want to access that drop later for yourself; it's not a feature that we will be using.
That's it! I'll get the link, download the pictures, and upload them for you.
Drop.io is a great service, and I'll be writing later with some ideas on how to use this great collaboration tool for staff development, homework, etc.
