revTalk - iRev - revWeb - PHP - iPhone and back again

[Thomas McGrath III]

Sarah, Thanks, I knew you were also learning the Obj-c stuff.

I wanted to do either show recent x number of images and or searchable  
images (top twenty) and update a page on new images or coming to the  
page. There may be thousands. I also want to write an iPhone viewer  
app to view these images. So an image captured on the device and  
manipulated in my app is then sent online. Online, (preferably iRev)  
will process the file and display the file and push the needed iPhone  
push code to the viewer app. Then I would want to provide some of the  
social aspects like voting/rating and sharing and linking etc. Down  
the road I would like to provide user password protected areas for  
manipulating a users uploaded files, etc.

I am also planning an app that would allow users to add photos and  
text to a page on the web for an individual user that would then be  
downloaded to another of my iPhone apps as an update. After being  
notified the user launches the app and it would check online for new  
data and download that and process it for the user. I can explain this  
one further but for now I just want to grasp the whole process for the  
app I already wrote and what iRev can do for it.

Then lastly the easiest part would be to have a desktop app like in  
your demo to display the images as well. I walked through your  
tutorial and built the sample app.

I might be able to trigger an iRev script - that would be cool and  
would help keep this in the realm I understand. Maybe that would be  
the missing piece for me.

P.S. I uploaded the PHP script I borrowed in another reply.
