Custom mandatory fields when posting an image?

[Stanley Lyndon]

Hello all,

I am thinking of creating a forum for amateur photographers where they can share their photographs. For now, I would like to stick with IMG tags and using external image hosting. But, when they use the IMG tag, I would like to have them fill out a specific list of questions like lens used, camera body used, aperture, shutter speed, ISO, WB, etc. They can have a default value for each saved in their preferences.

Is this possible? If so, how much would it cost approximately to get this done? It would be great if such a mod would be already available though I doubt it would.

Thanks in advance!
Stanley.
