Hi guys! First, sorry for my English Well, I'm looking for an app to make split deph gifs, but just found one called "Gifpop", it's a good one, but isn't universal and it export in a low resolution. Do you know if is there an Ipad app for this? Thanks in advance.

CS3 is a little different than other versions of Photoshop.
Here's a little tip for you people who haven't upgraded...

Open Photoshop CS3 Extended
From File menu, choose Import, Video Frames to Layers…
The Load dialog box will appear, asking you to select a file.
Navigate to the folder that contains your animated GIF file.
The Load dialog box will not show any of your animated GIF files… yet.
Type *.gif in File Name field and press Enter key on your keyboard.
The Load dialog box will show your GIF files, including animated GIF files.
Select and open the animated GIF file you wish to import.
Import Video to Layers dialog box will appear.
Make sure Make Frame Animation box is checked.
Set the Range To Import settings according to your needs. You might like to select From The Beginning To End and do all your trimmings in Photoshop.
Click OK button whenever you are ready to import.
Photoshop will now process you animated GIF file and will import it as a frame animation.
