Flickr does not force a maximum photo size of 1024×768. The full original, as uploaded, is always stored on flickr and the restriction is only if you opt for the free account. Once you go PRO all of your photos will be available in their original resolutions. As for a backup I partially agree with you there are better options out there like an external HD or burning DVDs (I do both and store the DVDs at a family member's house) but flickr can also be part of a comprehensive backup strategy. I know that for my family all the best photos end up on flickr so although it does not act as a backup for the thousands of photos we take it does host the best of the best and they will be available to me should the worst happen to my computer or the backups I have made. »

Are you running KDE4? KFlickr has not been ported to KDE4 as of yet and I seem to recall hearing this is the behavior of KFlickr when run in KDE4. You will have to wait until roughly late Sept. before the KDE4 port will be complete. »
