looking for img viewr that allows non-WP stored images

hi there, i haven’t been able to find anything similar to this Q? on the forums, but there are thousands of posts…

i have a semi photo semi regular blog on another site which ran into an image storage limit. WP has the same issues. i don’t want to ‘buy more space’ as i already have set up an unlimited storage for my images.

(from what i could tell nextGen gallery *seemed* to do everything i wanted except for img location)

however i need to pull them into an image viewer for my blog.

i don’t need all the fancy bells and whistles, but the following functionality is needed:
1-ability to step thru the images
2-ability to see how many images are in that ‘album’ or ‘gallery’
3-ability to see caption for each/any image

does *anyone* know of *anything* on WP that i can install on my WP blog that will do this? I’ve been trying to go through the image plug-ins but again there are so many of them and documentation on the ‘pull the image from a locale other than WP’ is very lacking. ??

i am now so far behind on my posts it’s pathetic ??
please help!
