What program do I need to change the resolution of a photo?

What program do I need to change the resolution of a photo that is currently a low-res .jpg? I previously had photoshop, but it did not transfer to my new Mac Lion - and it is too expensive to repurchase. Curious if there is there an alternative option? I cannot open hi-res files anymore, and would love a solution. Thanks!

Take a look at Pixlemator in the App Store

  • How do you change the resolution of a Photo?

    In iPhoto, how to you reduce the resolution of a photo in order to reduce the file size? This makes it easier to email because of the smaller file size?

    Let's say I have a photo with a resolution of of 3264 x 2448 pixels.
    Tat's not a measurement of resolution, that's the dimensions (length x breadth) of the photo, expressed in pixels.
    Resolution is a vague term most used to describe the density of pixels - i.e the pixels per inch.
    1) I want to edit it and reduce the resolution to 1024 x 768 pixels.
    No, you want to reduce the dimensions of the image to 1024 x 768
    2) Do this within iPhoto without using the export feature thereby keeping the edited photo in iPhoto?
    You can't. It can only be done on export. Why? When you edit a photo iPhoto preserves the original and makes a copy of the file containing the edit. As most people reduce the dimensions, file size or resolution for a specific purpose (to upload it for instance), it's thought best to export it, upload it nd then trash it.
    Of course, you can simply import the export back in, if you have a burning need of it in iPhoto.

  • I Need To Change The Resolution In A Graphic Without Changing The Graphic's Size

    I am trying to make a banner for a parade, and am stuck because the banner company can't print my design. I made my design with two different layers. I have a black layer which is 8 inches by 2.5 inches high, and the logo graphic which I have copied and pasted from the place which wants me to use this logo in the banner. This graphic has way too low of a resolution, so I tried to change it (It is 4 inches by 1.5 inches). I made the resolution of the first layer (the 8 inch by 2.5 inch) at 1000. I took the graphic and copied it and make it at the same resolution. However, when I tried to copy and paste the smaller graphic, it wouldn't let me paste it into the 8 inch by 2.5 inch layer. I got the message that the graphic was too big to paste into that layer. But the measurements for that are still the same; 4 inches by 1.5. If I could really keep that measurement at a resolution of 1000, it would work. What am I doing wrong this time? Thanks.

    First of all, there's no point in going over 300 ppi, since the eye can't detect any difference beyond that level. The answer here is still the same as it was when you asked back in June:
    Can't change image size
    So you would need to set the bottom layer to the resolution you want. However, 1000 ppi isn't going to look better than 300 or so.
    and in re your other threads, PSE doesn't do vector graphics.

  • How do I change the resolution of my photos on my iBookG4?

    I have iPhoto 6 and post things regularly on craigslist. With my older camera I never had any problems uploading photos to the web. Now, with my new 6 megapixel camera, CL won't always take the photos all at once. Is there a way to downsize the pixels within each photo so that posting on CL is easy again? This is driving me nuts. It used to take 3 minutes to post an ad and less than a minute to load the photos. Now it takes on average 10 minutes per ad because I can only load 1 photo at a time, and each one takes forever to load. iPhoto won't change resolution, just size of photo. If iPhoto6 won't manipulate resolution for me, is there a good free software compatible with my iBookG4 that will? Thanks.
    iBookG4   Mac OS X (10.4.6)

    Try File -> Export in the dialogue you can specify the original or a different size that you select. A little trial and error will help you find the correct one.

  • Where can i find the resolution of a photo? I need to change it to 102

    where can i find the resolution of a photo in iphoto? How can I change it to 102?  I see is the pixel  width and height, along with the mb/kb size for photo info; I need to change the resolution and size for submission.

    Short answer: the dpi (or resolution)  is set when you decide what size you're printing at.
    Long Answer: Dpi means nothing in the digital world of your computer. There are no "inches" to have "dots per..." Size is measured in pixels. That's the same on your camera. It doesn't take 10 x 8 or 6 x 4 shots. It takes shots measured in megapixels. For instance 4,000 x 3,000 is a 12 megapixel camera.
    Using that example, that shot from that camera has 12 million pixels. So that's how many "Dots" there are. To decide the ratio of dots per inch, you now need to decide the "inches" part. And that's printing.  Print at 10 x 8 and the dpi will be 4,000/10 or about 400 dpi. At 6 x 4 then it's 4,000/6 or 660 dpi. Work the other way: Print at 300 dpi and the resulting image will be about 13 inches on the longer side.
    So, your photo as a fixed number of pixels. Changing the dimensions of the print will vary the dpi, changing the dpi will vary the dimensions of the print.

    Perhaps you are loading a template that has a text block already on it.

    I've created a fillable PDF document in XI Pro. I need to change the body of the document and create a new fillable PDF document. When I do that it won't let me create a new PDF. It keeps saying "no new  fields recognized. What can I do to redo my document with the changes in the text, but no changes in the fillable fields?

    You start with a source / authoring file for the "static" content (e.g., Name, Last:). Say this is an MS Word file.
    You master the "static" content..
    You keep this authoring file and have a backup of this file.
    You output a PDF and use Acrobat to build and fine tune the "form" (form = the form fields, not the "static" content).
    The authoring file  and output PDF (with form fields) gives you "rev 00".
    Now, you must change something in the "static" content.
    Open the authoring file and save as to a new version (e.g., "wordfile_v00"  becomes "wordfile_v01).
    Output this to "pdffile_v01".
    Use Acrobat to open the PDF form file "pdffile_v00". Save As to a new file name ("pdffile_v00update").
    Using Acrobat XI Pro the click-path Tools - Pages - Replace lets you replace a page or pages of "pdffile_v00update" with a page or pages from "pdffile_v01".
    This replaces the "static" PDF page content and does not affect the form fields on the page.
    (you may have to adjust position of form fields)
    Save "pdffile_v00update" to "pdffile_v01" to reflect the revised status of the PDF form file.
    Be well...

    You may need to go back and start over.  Reset the router back to factory defaults, log on as the admin, set up security, DHCP, and make sure the IP address pool has enough IP addresses to lease to ALL of the computers/devices that will connect to that the router.

    4. In case any of the previous operations work but the settings don't "stick".  There are two plists associated with the settings:
    /Library/Preferences/com.apple.windowserver.plist
    ~/Library/Preferences/ByHost/com.apple.windowserver.XXXXX-XXXXXXX.plist
    The first is global to all accounts while the second is in your home directory.  The X's are a sequence of hyphaninated  letters and numbers.  If you can get these removed then it will probably revert to a default resolution.

    A calendar is not difficult nor does it take long once you know where the dates fall.
    Start with a basic month template table.
    1. Click on the table icon on the Toolbar to create a basic table for one month
    2. Click on the resultant table > Inspector > Table > Headers & Footers > 2nd button > 1
    3. Inspector > Table > Body Rows: 6 > Body Columns: 7
    4. Inspector > Metrics > Size > Width: 7 cm/in > Height: 7 cm/in
    You can drag resize the whole month to your liking afterwards
    5. Select the entire header row > Inspector > Table > Edit Rows & Columns > Merge Cells > Type in a month
    6. Type Mon in first cell & Tue in 2nd cell of of 2nd row > Select both cells and drag the white dot in the bottom right corner sideways to fill the cells with the days
    7. Do the same with the dates in the cells below
    8. You can fill the spare dates at the beginning and end of the month if you like and maybe change them to a paler grey.
    9. Style and position the text as you like it.
    10. If you don't want to see the grid or want different strokes, colors etc:
    Inspector > Table > Cell Borders/Cell Backgrounds etc
    When you have the first month looking the way you want, option drag out copies sideways to make the rest of the months.

    Hello SalsburgD
    The first thing I would check is to make sure that the router is using the recommended settings to get online. Another troubleshooting step is to create a new Network Location and then join your network to see if that changes things.
