Batch Resize Layouts for Web Galleries

(8 posts)

    Many web galleries have resizing policies in order to post images (digital scrapbooking layouts) on their galleries. I searched the forums and found a little information on my question, but nothing with a complete answer.

    Here's what I'd like to do with the Batch Resize feature in ACDSee 10 Photo Manager:

    1. Change a 300 ppi image to 72 ppi.
    2. Change longest side of image to a maximum of 500 pixels.
    3. File size maximum of 125 KB.
    4. Preserve aspect ratio so that shortest side of image changes automatically to the correct number of pixels. (When I check this option, it does nothing. I still have to manually set both the Width and Height pixels. Is this a bug in the ACDSee 10?)

    Example: I want to resize several 8.5x11 inch (2550 pixels x 3300 pixels), 300 ppi images to 386 pixels x 500 pixels, 72 ppi, 125 KB. When I check "Preserve original aspect ratio" and type 500 for the Height, the Width does not change. Also, I have selected Fit Within: Width and Height.

    Many times I have other rectangular or square sizes I want to prepare for the web. If Preserve Aspect Ratio does not work, I have to figure everything manually.

    ACDSee doesn't have a way to batch resize according to maximum dimension.  Best you can do if you want the dimensions to come out exactly is have two presets - one for vertical and one for horizontal images.  Or you can resize by pixel count, which given you a way of more or less approximately resizing according to maximum dimension if your images have similar aspect ratios.  And speaking of which, I've never the bug you mention where aspect ratios are not preserved - they always are for me.  But I haven't used version 10 much.

    As for the EXIF resolution field, there is never any reason to be concerned about that.  Whether the EXIF resolution field says 300 or 72 has no effect whatsoeve ron how the image prints or displays.  All that matters is how many pixels it has.  The *actual* resolution of the image will be determined by the size at which you print or display it, not by the contents of the EXIF field.  That numbr is not used for anything - it is a holdover from the days when the only digital images in the world were creating by scanning physical documents, not taking pictures.

    Thanks, Marc. Guess I'll just continue to prep images for the web in Photoshop.

    I'm using ACDSee Pro 2, so I'm not sure this solution is present in your version, but there is a better way to do what you want than what Marc suggested:

    I found the solution in another thread:

    http://community.acdsee.com/forums/topic/batch-resize-of-horizontally-and-vertically-oriented-images#post-16759

    Summary:
    * Use Tools > Batch Resize
    * Select "Size in pixels"
    * Set both Width and Height to the number of pixels you want the longest edge to be
    * Make sure "Preserve original aspect ratio" is checked
    * For "Fit within" select "Width and height"

    I believe you are correct - I was actually thinking of the Batch Processing tool, not Batch Resize, and Batch Processing isn't even available in PM10.  I rarely use batch resize because it has other limitations compared to Batch Processing, but it does have this advantage.

    Not sure what just happened to my most recent post, so I'm reposting it.

    Rosie, I totally understand what you're saying, but there is still one piece to this puzzle I cannot solve. Many sites, in addition to the dimension requirements, have a size requirement. For example, 125 KB. I cannot figure out in ACDSee 10 how to BOTH change the dimensions AND size of an image. For example: 640x480 at 125 KB. Consequently, I always revert back to Photoshop to take care of both these tasks where there are Image Resize and Save for Web features.

    What I do is use the megapixel option to get the pixel dimensions about where I want them, and then figure out a JPEG compression option that gives me about the file size I need, and save both of those as a preset (that's a pro-only feature).  This works only if it's OK to not get either the dimensions or file size *exactly*.  I find very few photo hosting services still require you to do any of this yourself - Flickr, Zenfolio, Photobucket, etc will also resize your pictures for you.  So my main resizing preset creates  file bigger than necessary for any of them, and they resize it how they see fit.  Then I have an presets for the couple of service that don't resize on upload.  For those, I do my landscape and portrait mode pictures separately, because I do want the dimension exact, but I don't care if my file size is *exactly* the maximum or not; I just choose a JPEG compression that reliably puts me under.

    Thanks, Marc and Rosie. I'll try out these suggestions.
