Since I will have one page per coin, the number of pages will be the same. When I first started looking for a free/cheap website with templates, I thought it might be good to do it with a map. Drop pins in the map, have pop-ups for each coin. Still think it is a good idea but I just couldn't make it work nicely. Plus, my map would have most of the pins in certain Ionia cities and in Alexandria. I'd love to see someone else do the map thing though. I've seen a few ancient coin websites which have limited clickable maps but none that were done elegantly.
Unfortunately, I doubt you could do a map with a template style website. You'd have to code and add images manually and update it the same. It would not be easy. I used to work on sites all the time and I have used a image coordinate map before. Maybe I can brew something up later, but honestly I've had a difficult time focusing on stuff like that lately. Oh well.
It would be possible to make a killer map-based coin site using Prezi. www.prezi.com Instead of traditional hyperlinks, everything is contained on one page and you zoom in and out to move around. For instance: - background is a large map/overview. Tiny dots marking coins - click a tiny dot... ZOOM! You fly into the map, seeing a smaller area with thumbnails of the coins. - click a coin... ZOOM! full screen of that coin and its info. I used the zooming in a more limited way when making the Pink Floyd / Animals presentation http://prezi.com/q7mw1k1zur65/pink-floyd-animals/
That's actually pretty neat and I like how you can zoom in and out. Might want to try a map and see how it works out. There are a few but I'm not sure how usable they are.
I think geographically would be better, I don't want to have to do the whole 'looking for Alexandrian tets and then be finding stuff from Cilicia.
It is quite possible to do both lists. Upload photos with a generic name and call up those images in more than one folder without uploading a second copy of the image (which would eat up the allotted space). I have done this on pBase but suspect it is possible on others. The lead image of my site is mapped so clicking on a coin takes you to the page on that coin. Writing that routine was tedious but I assume there are canned software programs that automate it. I am working on a new mapped image leading to 100 different pages but writing the 100 pages is no small task and I'm only half way through. Having too many coins to show is such a burden. Start a project like this before you get so many coins that you will never do it.
