Actually we only have 1 front-end server, but planning to move into a webfarm with multiple front-end server and 1 access point datastorage("SAN/SAS") to stores all the photos/videos.
Actually we simply use <img src="/images/somepath/image.jpg"> to display the image on client site. But we will not be able to do so eventually cause we are moving into webfarm and datastorage.
Someone told me that i need to create a "Image Handler (ashx)" who return the images.
What about the performance and memory load of using a image handler to display images. And what about "file lock" if 2 front-end server try to send back the same images?
