Downloading High Res Images

Trying to get a folder in place for high res downloads.
While I can upload my images, I get no thumbnails, when I edit the thumbnail and resize the image the screen goes black.
The folder is password protected, and is used for event photography.
My questions is simple, is there a limit to file size?
Below is the file details.
Size: 14.4Mb
Thumbnail: iv-includes/images/thumbs/jpg.jpg
Width: 7360
Height: 4912
Type: JPG

Unfortunately, there are two problems here ... The main problem, is that your server is not powerful enough to create thumbnails from images of that size. Second, there is a memory limit inside flash of approximately 4000 x 4000 px dimensions ...
I would question though, how practical is it for a visitor to be viewing 14MB photos in a slideshow? Would take several minutes wait just to a view a photo before one could view it, even on fast connections.
There is a special setting in imagevue under admin -> settings -> controls.altimage. It allows you to create a folder "_altimage" inside a normal folder, where you can store high-resolution versions of your images. So basically you have a folder /myphotos/, with normal web sizes for nice fast viewing at normal screen sizes ... You may be viewing an image /myphotos/picture.jpg - When someone clicks "download" or "view in popup", it looks for the same filename in the corresponding folder /myphotos/_altimage/picture.jpg (which is of course the high-res version). This would solve your problem, because thumbnails would be created, and you can have normal viewing of images, yet downloads will be in high-res.

controls.altimage
<altimage type="boolean" description="Sets an extended folder path '_altimage/' to open a different version of selected image. Effects the functions popup, window and download image">false</altimage>
