Google makes the really neat program Picasa 3 for managing and editing photo/image collections. Since Microsoft Windows it a travesty and I therefore use Linux as much as possible, I was in need of a better and more stable photo management software to replace the buggy unstable F-Spot program. To my glee I found that Google releases a Debian version suitable for using under Ubuntu’s flavor of Debian Linux. I love you Google. Anyway, it was still a 2-step process, which would frighten most Windows users, but this bit of work in the beginning assures that I am using reputable sources for software that can be installed without visiting a website or downloading anything from a web server, as I would have to do if using Windows. Not to mention that by being forced to the wild web in order to download all applications and software just opens up a computer to problems because the user must decide which software makers to trust, not a good situation for casual users who aren’t in touch enough with the current “scene” to be able to make an educated decision about which company’s software is trustworthy and which are not. Alas, I digress…

To install Picasa on Ubuntu:

1. Create a backup copy of your file: /etc/apt/sources.list
2. Edit /etc/apt/sources.list using “sudo” and the editor of your choice e.g. vi, vim, gedit.
3. Add the following line:
   deb http://dl.google.com/linux/deb/ testing non-free
4. Save the file.
5. Update apt-get’s repository list using: sudo apt-get update
6. Try to install Picasa now: sudo apt-get install picasa
7. If it installs, then Hooray! You’re done! However, if you get an error like the following, then proceed to the next steps:
   W: GPG error: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 1234567890123456
   W: There is no public key available for the following key IDs:  1234567890123456
8. The long number will be different for you, and you’ll need it for the next step.
9. Run the following commands, substituting 1234567890123456 with the number from your error messages:
   gpg –keyserver pgpkeys.mit.edu –recv-key  1234567890123456
   gpg -a –export 1234567890123456 | sudo apt-key add –
10. Assuming that you get success, and you should as long as there’s no typos, try again to install Picasa directly with Ubuntu apt-get:
    sudo apt-get install picasa
11. Picasa will download and install, you may be required to verify that process before it proceeds, though.

Check put these for a bit more info, and the source of the steps needed for this process:
[Debian] Apt-get : NO_PUBKEY / GPG error
Howto Install Picasa 3.5 in ubuntu

Posted under Freeware, Graphic, Linux, Software

Using Adobe Illustrator CS4 (this procedure may also apply to CS3 and earlier versions, please let me know if it does) you can make a neat little object that looks like it is curved, rounded, and shiny, with a light shine highlight and edge darkening effect to get the full depth.

1. Start with an image layer, containing the image that will be the skin of the object (which is in our case a round convex button).
2. Put a new layer under it.
3. On the new layer create a circle (Ellipse (L) tool and hold Shift to force circular, hold Alt to anchor center point of ellipse while manipulating the size) that encompasses the part of the image that whall be visible on the final “button” to be created.
4. Create a radial gradient in the circle. Make it lighter in the center.
5. Create a new layer between the image layer and the circle layer.
6. Create another circle on this layer, a bit smaller than the last one, and shifted down a bit so it almost touches on the lower boundary of the circles.
7. On the same layer create an ellipse that is larger than the circle, but leaves a crescent at the top of the button, for the shine.
8. Using the layers box, and holding Shift, select both these layers. Then click Pathfinder > Subtract From Shape. This trims out all but the crescent.  (If it does the opposite, Undo (Ctrl-Z) back and reverse the order stacking order of the circle and ellipse on this layer, and try this step again.)
9. Create a new layer between the image layer and the original circle layer.
10. On this layer create a rectangle that covers the entire crescent.
11. In the rectangle, create a white-down-to-black gradient (at -90 deg.) using the standard black and white color pair.
12. Using the layers box again, select both the rectangle and crescent layers.
13. On the Transparency panel dropdown (located in the right-corner of the panel) menu selet Make Opacity Mask.
14. Select the original circle and copy it.
15. Select the image layer, and paste the circle using Ctrl-F.
16. Select the pasted circle. Remove the fill and stroke from it.
17. Select the entire image layer (which selects all sublayers too) and do Ctrl-7 to create a clipping mask. Now your button looks round.
18. Create a new layer above the image layer, but under the shine layer.
19. Paste the circle again into this new layer.
20. Convert the fill to a B&W gradient.
21. On the gradient, move the center nugget toward the black as far as it will go. This creates a domed shadow effect.
22. In the Transparency panel, select Mode of Multiply, then select Opacity of 20%.

Viola! Now you have a round  button that looks roundy and shiny.  Rotate the crescent layer to change the direction of light in the shine.

Great Adobe Illustrator tutorial I got this metod… thank you Veerle!
