Re: 2 Suggestions
Set the max file size for images to 640 x 480 in the 'Edit Filetypes' link in your admincp. Make sure 'Save Original Files' is set to 'Yes' in your main options. Then in your 'ADV_GALLERY_SHOWIMAGE' you should see the <if condition> for original images. Change the link there to point to $image[url] rather than showimage.php and add target="_blank".
