If, like me, you have digital photo’s stretching back to the early days of digital cameras and even scans of film and slides, then you may have the same issue I had attaching the right date to the file. I have over 35,000 digital images, so developed a little command line tool to help called ‘Image Processing Console‘ (https://github.com/nrogoff/ImageProcessingConsole).
Rather than trying to create all these by hand I have created a Photoshop script to generate all the variations from a portrait source and a landscape source. You can download this from All Mobile Splash Screens.js The source images must be 1536 x 2008 for Portrait and conversely 2008 x 1536 for landscape. Due to variation in aspect ratios, If your splash screen has a logo or text of some sort it’s best to make sure this lies with a of 204px left and right padding area for portrait or top and bottom for landscape.
for example, you can see below all my ‘important’ stuff is inside the bleed area.
If you are really clever then you can start with a single image for both keeping the logo or text within a central box of 1004×1004 as shown here.
Use Photoshop Script
Copy it to your Photoshop Presets/Scripts folder. Mine was at c:\Program Files\Adobe\Adobe Photoshop CC 2014\Presets\Scripts and I create a subfolder to hold my scripts. On a mac or if you have the 32-bit version your local path will vary.
Launch Photoshop and you should now see the script available under File->Scripts called ‘HMS Create All Mobile Splash Screens’
Open either your Portrait (must be 1536 x 2008) or Landscape (must be 2008 x 1536) source image.
Then run the script by selecting it from the menu.
If you have a landscape just repeat the process for that.
This will generate a series of cropped and new resolution versions of your original image in the same folder. If the source image is not exactly the right size the script will tell you and exit. You should end up with something like the set below, where all the test is still in frame.
