I have made your post a separate topic since it clearly had no place in the Bugs and Suggestions thread in which you posted it.

I just made this video specifically for this topic:

Batch Process Images to 300 ppi

So hopefully between the instructions listed here and the video the method should appear pretty easy.


So the first thing we want to do is create a script. This will let us resize the images all properly.

1) Open up any image

2) Go to your Script Toolbar and hit the red record button. If you don't have your script toolbar open, go to View -> Toolbars -> Script to bring it up.

3) Select Image -> Resize from the menu.

4) In the resize dialog make sure Advanced is selected at the bottom of the dialog, and that Lock aspect ratio is selected.
Set the Resolution to 300 Pixels/Inch

Set the Pixel DImensions to 100 Percent on both the Width and the Height.

5) Hit OK to make the change.

7) Next hit the "Save" button on the script toolbar (diskette symbol)

8) Give the script a name like Batch300ppi

---

Now that we have our script we're ready to batch process.

1) Go to File -> Batch Process.

2) Click "Browse" at the top of the dialog to find all of the images that you want to process

3) Make sure "Use Script" is checked. ANd that our script "Batch300ppi" is the script selected in the drop down box.

4) Also make sure Silent Mode is checked. This will hide the dialog box so that it doesn't pop up for each image. And we don't need the dialog box for this.

5) If you want them all to have the same type, and that type is different than their current type make sure that "New Type" is selected. IF they are all already in the file type that you want, go ahead and make sure that "Copy" is selected.

6) If you selected "New Type" you can decide the file type in the next drop down the lets you pick from all of the types PSP supports. And you can adjust their settings by clicking on the "Options" button.

7) In the FIle location box select the "Browse" button. This lets you define a new folder to put the converted files into. I prefer to do this as it prevents any accidents from destroying my originals. Technically we should have nothing to fear from this script as it doesn't do much. But I recommend saving to a different location just in case.

8) If you want to give each file a custom filename you can do that as well. Filenames can be based off of custom text, original filename, sequence, and time of edit.

Once you have all of the settings you want, go ahead and hit the start button. PSP will start batch processing your files.

THANK YOU!!!! YOU ARE A LIFE SAVER!!! I AM GOING TO TRY IT

[Pinky]

Hi leviFiction! Again, THANK YOU. By any chance can i also resize of all pictures to a certain size during the same process. My book size is 6X9 and I am striving to figure out the proper size. I am self publishing so I have to do everything.

[LeviFiction]

That is possible, yes.

My question is, are you talking a specific physical size or a specific pixel size?

I'll just start with, the current method will only work for a specific image size if all images are the same size right now. IF the sizes vary at all then we need a new script.

---

If all images are the same size then resizing all of them to a specific size is easy.

Re-record the script but instead of using "Percent" as we did last time, use pixels and give it a very specific size. Once everything is set. Save the script.

All images processed with that script will become the exact same size.

---

If all of the images are different sizes then you run into the problem of image distortion if you use the method above. You'll need a custom smarter script that can look at each image and determine how to resize it to fit a few parameters.

I do have a script already made that we could use, however, for this it might be easier to just use a software like IfranView for resizing.

You could use Irfanview to resize and change the resolution all in one go. You can make the short side all the same size,or the long side all the same size, the width of all to a certain size the height of all to a certain size, or change all to a certain percentage. Its also a free program as well.

Hi levi, Thank you for responding! I am talking about the physical size. if possible , can you please send me the script for changing the pictures to 2x3 - the size of a business card
