    Hey there everyone. I just imported all my pictures from my PC to my Mac by DVD, and there is no pictures for a thumbnail, just a jpeg symbol. I tried to convert some RAW files to jpg, and they showed up the same way. I've tried everything I can think of. Any suggestions?

    It seems to be related to the creator (the app). If you open and resave with something like PSE, the correct thumbnail will appear. I never worried too much about it myself because I use iPhoto exclusively and, of course, it doesn't matter there.

    happens to me sometimes. in that case i use spacebar to preview the file as it doesn't open an application to do so.

    weird!
    I have a Macbook and a few PCs. I imported all my photos and I can see them as thumbnails.

    Using Leopard.

    Ha! Didn't know that worked. Thanks for the tip.


    Now, I am not 100% sure, but I believe the thumbnails are only shown if the exif info contains a thumbnail. So, if you save using PS's save for web feature, all exif info is stripped from the image and when you look, there is also no preview image in Finder.

    It's kind of a pain in the arse that it won't come up, but I can deal with it. I was watching a video on YouTube for Mac tips and the guy had thumbnails on his so I figured it could be done.

    I have a couple pictures with thumbnails, but they were saved to the desktop instead of a folder. I just tried to do that and it didn't work this time... The EXIF data stays intact when I post them to the web, but I can't seem to save a preview. It does work on my PC.

    As for iPhoto, I only ever tried it once and I could not get it to import any of my pictures. I guess I can give it another try. Anybody have an quick ideas what I may have been doing wrong the first time?

    Well, there are also some software solutions out there that will batch create thumbnails in your images so that you can see them as icons in Finder... maybe Google for them?

    What happened when you attempted to import?

    Last time it moved all the pictures into a iPhoto folder, but nothing would show. I just reattempted it, imported from the iPhoto folder and everything works great now! From now on how do I go about having it automatically import to iPhoto though?

    And since there is a few Mac guys here, is it best to buy a new iMac with 4gb of ram, or just upgrade my Mac Book to 4? It's only got the Intel Duo core, where as the iMac has a quad core. Will I be able to run Photoshop CS3 on the Macbook with 4gb ram?


    So many questions.. sorry. I'm supposed to be studying for finals, so thinking up questions for you guys is what I spend most of my time doing!

    Thumbnails appear when they are part of the image file. That is to say they are attached to the image - but this is not done automatically. The thumbnails have to be created.
    Saving files with something like Photoshop can generate thumbnails, but it is not an automatic thing - although the default is to create a thumbnail.
    In PS go to the top menu bar >File >Save As... will open up a dialog to select how and where the image is to be saved. Clicking Save brings up a second dialog box for JPEG giving compression options. There is (or should be) a check box marked Preview. Putting a tick in this box will create a thumbnail when you save. Leaving it unchecked won't.
    Other formats like TIFF don't give you the option, they just do it.
    Other image programs may do things differently but they usually include the Create Preview option somewhere. If this has been turned off then saved images won't have a thumbnail.
    Macs do their best to provide a thumbnail - even for video. But some file formats it can't cope with.
    If a preview is embedded in the image it will show up.
    If the Mac can read the file type it will show a thumbnail.
    If there is no preview and the Mac can't read the file then you will get a generic 'file type' image. This will say JPEG or TIFF or...
    Generic images are often produced to indicate the program that created - or has been allocated to deal with - the image.
    I use VLC player for .WMV videos. The icon for these files is the VLC icon. But if I then open one of these files with Windows Media Player the icon is converted to the WMP icon because my actions tell the Mac what program I want to handle the file.
    Any image or video that comes up with the plain document image (white rectangle with one corner turned down) means that the Mac does not recognise the file type, cannot read a thumbnail and does not have a program that can handle it.
    PC viruses tend to have this icon on a Mac ;)
    Finally imported files should be allocated a relevant icon unless the file has been locked. This can happen for a number of reasons, often when the file is imported from a CD, DVD or external HD. Highlighting the file and pressing 'Command' + 'I' will bring up the information dialogue. At the bottom is 'Sharing & Permissions'. This tells you who can do what to the file: read & write or read only.
    Sometimes when importing files the Mac assumes you are third party and sets this to Read Only. If you are logged in to your Mac as Admin (and if it's your Mac then you should be) you can use the Info dialogue to change status.

    A good program for image handling - it will convert image types, create thumbnails and do other stuff is Graphic Converter.
    If you use a Mac and don't have this, download a copy. It's a life saver and you may never need another graphics program.
