With a 100MB upload quota, running out of space has been a problem for many site owners using images on blogs.evergreen.edu. For most, the issue lies with uploading high resolution, unprocessed images straight from a digital camera to the image library. These images then get scaled down by WordPress for the web but the original still hangs out in the media library taking up valuable space. We often see image files uploaded to WordPress in excess of 7MB in file size and over 5000 pixels wide. When people view your images on your blog however, WordPress is delivering a scaled down version, typically at 500 pixels wide max.
For Fall of 2014 we’ve implemented a fix that will hopefully solve this issue. We’ve activated a network-wide plugin that automatically resizes images on upload to a max of 1200 pixels wide and discards the original high resolution version (site owners are responsible for keeping copies of original images somewhere safe). With 100MB of file space you should now have room for over 600 images . The settings to control the image resize on upload are found in Settings > Resize Image Upload.
