Image Size in Adobe Bridge

Is there any way to see Image Size from within Bridge. I know that you can see it if you open the file in Photoshop, but I don't want to have to do that for each image just to see the image size. It is not an option to have it listed in the metadata as far as I can see. You can list resolution, file size and dimensions, but not image size. I want to use Bridge to upload images to Adobe Stock, but there is a 4MP minimum image size requirement. I have no way of finding the image size easily. (I could calculate it from the dimensions in pixels multiplied by the number of channels, I think, but I'm not exactly sure -- plus I don't want to have to do math!)

    Correct answer SuperMerlin

    Yes, SuperMerlin, you are correct, but that is way off topic. All I wanted to know was weather the Image Size value is listed anywhere within Bridge. Do you know? I'm guessing it's not since no one has jumped in and said so.


    No it isn't but a script can display that information for jpeg, other file types would be more difficult.

    You can request it to be added @ Photoshop Family Customer Community

    First of all, you really want to upload larger files than 4MP.

    Second, bit depth has NOTHING to do with image resolution (megapixels.) Megapixels is an area measurement, width x height.

    1633px x 2450px is the closest 2:3 ratio size for 4MP.

    Just do the math, a cheap desk calculator is a good friend.

    Came across this whilst trying to solve a similar problem. You can [kinda] do this in bridge.

    A 4 Megapixel image works out at about 2667 x 1500 (16/9 aspect ratio). Do a bridge search for images where width and/or height is greater than 2667 and you should [strange crops aside] get all of your images that are 4MP and above.

    You can also filter for file types to cut out any PDFs or other strays.

    Agreed, this is what I mentioned in my reply #5. The MP inspector panel is also helpful too.

    Unfortunately, that is file size, NOT image size. I need image size. File size (measured in MB) is the number of bytes the file uses on your hard drive. The image size (measured in megapixels) is the number of pixels in the image. You have this info in the image size dialog box in Photoshop but I find it nowhere in Bridge.

    The MP size in my 3168x4752px example is 15.1, while the Image Size is 43.1MB … I don’t see the MP size listed in Image Size?

    I have not tested this, but thinking out loud you should be able to come up with a Bridge find command to use with a Smart Collection that would filter out images below a certain pixel width and depth, which would effectively give you a threshold for a specific MP size. This would be the best option as it only uses Bridge and would dynamically update based on the resolution of the images.

    Another option would be to use ExifTool to write the Composite:Megapixels tag value to standard metadata used by Adobe into a batch of files. I would use keywords. Then I would use the Keyword filter in Bridge to filter out images that were under the minimum required size. Not a one step process, however it is automated enough not to be too tedious, however the drawback is that you have to run the ExifTool command on new images (and it will no longer be valid if you crop or resize), while the Bridge Find command and Smart Collections are dynamic.

    Work on copies of the originals while testing as this command overwrites the originals, or you could remove the –overwrite_original_in_place argument from the command until you are sure:

    exiftool -r -overwrite_original_in_place '-subject+<${Composite:Megapixels}' 'mac os/path to input/folder'

    This command line code is from the Mac, on Windows simply change the single straight quote/foot mark ' to straight double quote/inch marks " with the correct platform specific path to the top level folder. This command will process all files from all sub-folders under the top level input folder. Further arguments can be added to restrict processing to specific file types or to ignore specific named sub-folders.

    Otherwise a custom Bridge script could show this info in the inspector panel, or possibly create smart collections etc.


    My question was simply if there was a way to easily see the Image Size value from within Bridge. I need the same value listed in Photoshop as Image Size in the Image menu's Image Size dialog box (in "M", which is megapixels, not megabytes). Click on the Image menu in Photoshop, then select Image Size.... At the top of this dialog box is the number I want to see in Bridge. (This is the product of the dimensions in pixels and the number of channels (if 8 bits/channel; double it if 16 bits/channel.))

    After this lengthy discussion, your answer seems to be that no, this information is not provided within Bridge or if it is you don't know where to find it.

    Thanks for your complicated work-arounds, but I'm not interested in that. It is less complicated to simply open Photoshop.
