Open one of the images that you want to resize and save.

Click on Window, Actions to open the Actions palette.

Click the “Create new action” icon at the bottom.

Name your new action and choose an F-key.

Click Record.

Now Photoshop is recording EVERYTHING you do. So don’t do anything that is unique to this image…

Resize it to the dimensions you want EVERY image to be.

Then click the Stop button.

You now have a new Action in the palette – so anytime you want to perform this resizing, you just hit the F-key.

Usually bitmap files are in indexed colorspace, so you can’t work with layers.

You’ll want to change it to RGB, and then in the layers palette, double click on the background layer to put it into an editable layer.

At this point, you’ll end up saving it out as a jpg or gif – so if you want to get it back to bmp you have to flatten it, return it to indexed colorspace, and then save over the original.

You can create an Action and assign it to an F-key – that’s the easiest way I’ve found for this kind of thing.

Open a psd file you want to save as a jpg.

Then click on Window, Actions. This will bring up the Actions menu.

Click the “Create New Action” icon at the bottom of the Actions menu. This will bring up a new window.

Name your action (something obvious, like “Save as JPG”). Select a function key from the list (and remember what it is so you can use it later). Then click the Record button.

Now, Photoshop is recording EVERYTHING you do… so at this point, take the steps you need to convert your file to the proper colorspace, flatten it, whatever you would do each time before saving as a jpg (if you change the image size or resolution, this is also recorded and any future images will have this same size and resolution – so only record the things you want to happen EVERY time). Then – save it as a jpg.

Then click on the Stop button at the bottom of the Action window. You should now see a new action in the list with the name you gave it – and anytime in the future you want to save your file just hit the F key you set to this action.

Photoshop cannot save an animated gif – it will only save the first frame. You need to save it as optimized in Image Ready.

Open the animated gif in Image Ready (make sure all the frames and layers are there, that this isn’t the file Photoshop created). Click on the Optimized tab in the upper left corner of your image, and choose the settings you want. You can play with the number of colors, dithering, etc, until you get the smallest file size you can while still maintaining acceptable images. Then click on File, Save Optimized As… and save it.

Open your original file and click on the Image menu. Choose Mode, and select CMYK. It will ask you if you want to flatten the image, keep in layers, or cancel. If you want to keep your layers, choose that one. Then save it (as a new file if you want to keep the RGB version as well).

If you have created the file in less than 300dpi resolution, you cannot upsize it to 300dpi without a lot of pixelization occuring. In that case, you will need to redo the artwork.

To check your image size, choose the Image menu again, and select Image Size… This window will show you your resolution.

You can increase your dpi IF you reduce the actual image size by an equal amount. For example, if you have a 72dpi image that you want to upres to 300dpi, that is approximately a 4x increase. Therefore, you have to reduce the pixels across and down by 4x. Meaning, if the image is 400 pixels wide by 400 pixels high, you would have to make it 100×100 to compensate for the corresponding increase in dpi.
