I had a problem with iFlickr where it would open but only stay open for 5 seconds and then crash.

I found out that even though I deleted the blank pictures in the photo album that iFlickr put in there it still left an .xml file behind. I don't know why this caused a problem but when I went in and removed the .xml files iFlickr now works again.

SO all you have to do is go to the photo folder via iPhonebrowser or any other iphone access program and delete any .xml files

That folder should only have the Dat file at the top and files with THM and JPG but not any XML files.
