I need to build a website that allows event attendees to easily download photographs of themselves in front of a step & repeat. The site does not need to be live at the event (though if there is an easy, simple and cheap way to do so I'm all ears); turnaround will be 48 hours.
I was thinking of using Lightroom's web module to build a simple index of a grid of images and then captioning the individual images with a link to download the hi-res. That seems straightforward and simple in terms of both creation and end user interface. Delivery of hi-res to the client will be via DropBox, so the links can point straight to these files.
Might there be a CMS or service that would be simpler that I'm not thinking of? Any pitfalls I'm missing with my current plan?
Thanks in advance.
