I've just downloaded photoQ and the iq2 theme, which I love. I only have two questions/requests right now:

1) Can the exif data be stored as a map (hash, dictionary, associative array, I'm not sure what they call it in php as I've never coded in it before) so the presentation of the exif data is more flexible? There's two things I'd love to be able to do with this:
a) output the relevant exif data in a more compact form, e.g., "1/125 @ f/5.6, 80mm, -0.33 EV, ISO 200"
b) generate a "maximum print size" from the image size params, e.g.: $ExifImageWidth / 200 + " x " + $ExifImageHeight / 200 + " inches"
For the first, some sort of templating function would seem to be the most flexible, while for the second, it be much harder to generalize. I'd be fine with hacking the php to do the second for me.

2) Are there any plans to be able to write exif data back into the originals or rename them? Generally, I upload my images, then name them later, and it'd be nice to have that data in the image's metadata or filename. This isn't nearly as important to me as the (1) is, it's more of a nice-to-have. However, it could be used in conjunction with the first one: if you could set the resolution exif fields (and height and width fields if not defined), computing (b) for display would be pretty trivial.

Thanks for such a great plugin,
Barclay

1) first of all, the next version of photoq (which i will probably release next week i nothing unexpected happens) will include a new form of exif handling that is more flexible. with these new features you will basically get a) for free.

already today you can get a) and b) as there actually is an associative array with exif data stored with each post. it is in the custom field photoQExifFull, for details see the documentation.

You can also find an example of how to use it in your template in comment number 24 of this post: http://www.whoismanu.com/blog/2008/09/photoq-wordpress-photoblog-plugin-15-brings-tons-of-new-features-to-your-photoblog/

2) no, writing exif data is not really planned. right now it would not even be possible as the exif library i use is only able to read. i might however change the exif library in the near future so that photoq will be able to handle iptc metadata but i cannot tell you right now what this would mean for writing exif.
