hi michael,
thank you for posting here. i would be happy to participate in any way that is helpful for something like this. i should also probably have a bit of a think about a more thorough answer to your question but off the top of my head i would say the following. please keep in mind that i am somewhat tech savvy and understand scripting but i am not particularly code savvy.
1. i am surprised at how relatively difficult this seems to be vis-a-vis my WP website. i am planning on setting up a portfolio website as opposed to a WP blog and i really could use something more automated for this.
2. the workflow with Aperture to Flickr is almost seamless for me now that i have arranged my images. some quick caveats below.
3. metadata on my web published images and pdf’s is really important so i am finalizing all of this now in my various databases. being able to /update/ added or /changed/ metadata is super important. my understanding is that the plugin i purchased about a year ago may have been updated to do this whereas it was not able to do this in the past (at least to my understanding).
4. it is extremely helpful and necessary to be able to UPDATE and/or CHANGE existing Albums in Aperture (if i have new images to add to a project or if i decide to take out images or if i finally get my LOGOS together and put a logo overlay with copyright information on all my images…) – so – since it is so easy to update this in Aperture it would be huge to be able to do it easily for the WP album. Aperture is not quite perfect with this for Flickr but i think it is reasonably straightforward. Basically my understanding is that rather than select the whole album and republish you have to select just the added images and republish them and quite frankly now that i write this i am not sure how you DELETE images from an Album while in Aperture.
5. if you browse the Aperture plugin pages there are some very good plugins, very nicely presented and it seems like a very rich environment to present work in. FYI i have printed this list out and studied it to see what i need to optimize my productivity.
6. i think the Adobe equivalent to Aperture is “Lightroom” and frankly i would purchase lightroom if i could get this functionality out of lightroom and obviously i am sure a plugin could be modified to work in LR.
anyway, i see you have another post here which i will review. please let me know if i have left anything out. i will take a closer look at the link you kindly provided and i can also give you my email address if you want to follow up offline.
again many thanks,
jon
