eHive is adding some new features for images. You will now be able to upload larger images and have tools to pan and zoom into the detail. Original size image are now always stored, so you'll need to make sure you upload the size of image you want to permanently keep on eHive.
In the past eHive would have automatically reduced the size of images over 800 x 800 pixels. Going forward you will need to make sure that the images you are uploading are the scale you wish to display. In some cases this will require you to resize your images prior to uploading them.
