IPTC to caption/keywords support (patch for 1.3.3)

Hi there,

Gallery is great, but my carefully crafted IPTC metadata was lost when I added my JPEGs to the Gallery.

So I hacked IPTC support (for picture import) into the 1.3.3 sources - works great and shouldn't have any negative side effects.

I don't know how the patch will display in this forum - just mail me (at

) if I should send it to you by e-mail.

I'd like to see this in a working gallery. Can you provide a URL? Is this something many people are interested in?

You can use the patch utility to patch your Gallery.

Very nice instructions. Beckett, the current maintainer of G1, is on travel right now, but it should get noticed after he gets back.

I'm delighted to have discovered Gallery and especially the possibility of using IPTC information that I have embedded in my JPEGs. But I have a problem. After downloading the patches I get

Fatal error: Call to undefined function: getextrafields() in /Users/Shared/Web80/gallery/view_album.php on line 260

I've tried to find similar errors in the Forums with no luck.

Can anybody please help?

Thanks

Jeremy

Which version did you patch? 1.3.3 or 1.3.4? Have you applied any other patches?

see, this patch was written against 1.3.3. There have been a lot of changes, so it may not work against 1.3.4. Apparently it doesn't

Two choices:
1) fix it, and publish the new patch here.
2) use 1.3.3 and wait until someone else updates this patch, then upgrade to 1.3.4 and patch it.
**UPDATE**
3) or wait for 1.3.5, which should have this built in. No ETA yet on that.

I love the IPTC patch that I applied to Gallery 1.3.3. It made Gallery twice as useful!

But how do I upgrade Gallery to Release 1.3.4 without losing the ITPC suport. The site mentioned above by dave_spa doesn't seem to be reachable.

Thanks,
Tim
