I had a chance to look for Bibble, Silkypix etc two days ago. As expected they have not reached Bangkok which limits my choice.
I looked at Adobe Photoshop but that was too big and complicated for my needs. I also downloaded a free version of a very similar Programme but because it was free too many functions had been removed/stopped and again it wasn't much different from Photoshop or as good as the Gimp.
Eventually I remembered I had the Corel Draw Programme but had never used it.
When I installed their Photo Album, I discovered it did all and more than Picasa did. Basically back-ups go onto a CD rather than the hard disk and the rubbish that Picasa had collected was mainly ignored. I still have some tidying up to do but we are now heading in the right direction. Picasa has now been sent to the garbage bin and my computer performs better again
So for now I am using Corel for basic editing and storage, the Gimp for major photo alterations and printing via Corel which seems to be much better than the Picasa route.
I will of course keep an eye open for Silkypix and Bibble.
Many thanks for all your input.
