hello Steve,

I am really sorry for the delay of this reply as it is a weekend for us here.
Unfortunately that was no option for configure this in current system.
Because default behaviour currently as most of the time, user's / site owner's wouldn't want to use the original size since most of the time, the image itself is pretty huge and make the page load spend a lot of time.

by the way, if you really want this, you can modify this file everytime you update Easyblog in the future -> JoomlaFolder/components/com_easyblog/themes/dashboard/system/media.php

//LINE 98

					maxVariationHeight: '<?php echo $system->config->get( 'main_media_manager_image_panel_max_variation_image_height' ); ?>'



//Replace with



					maxVariationHeight: '<?php echo $system->config->get( 'main_media_manager_image_panel_max_variation_image_height' ); ?>',

					defaultVariation: "original"

After you done this code, everytime the user upload a image from media manager and insert the image file in your creation blog page, then it will show the original size.

Hope this help.
