GIMP Not Recognising JPG, PNG, etc. Files

    (posted this to the GIMPUsers.com mailing list, but figured that I could get help faster here)

    I recently upgraded from Windows Vista x86 to Windows 7 x64, and am in the process of reinstalling my old programs and restoring my settings. I had reinstalled The GIMP (version 2.6.7, x86 version) and was about to use it when I found that it couldn't handle any image files at all, other than XCF. I could neither open nor create any file other than the default GIMP XCF file format.

    I had tried anything I could have thought of, including reinstalling GIMP and associating the file formats, and transferring the old settings and binaries that had worked (the old plugins library, program files folder, etc.) from my Windows.old folder into my new Windows installation, to no avail. I'm not sure what I'm missing here, or what's being incompatible here.

    I frequently use The GIMP for photo-editing work and I am absolutely lost without it. Could someone help me out here? Thanks.

    .xcf files will preserve layers and is gimps file format. you won't be able to use it for posting anywhere. you should always save a version of your work as a .xcf file so that you can edit later. .png, .jpg and .bmp will not save layers.

    .jpg file format is actually a compression function. every time you save as .jpg it will compress the information a bit more. therefore you loose quality. so save as .xcf until you are satisfied and then save as something else like .jpg. .jpg, as stated by david, does not support transparency. so if you have a rectangle with rounded corners, you will see a background square corner when you post.

    .png is not lossy (does not loose information when compressed) and supports transparency. but the files tend to be larger.

    .bmp files are not lossy and support transparency. they are mostly used in windows based machines. they are large files as well.

    so, always save in .xcf until you get what you want then save a copy in an appropriate format for your use. you wouldn't for example save something in .jpg that you are planning to print. also there's no need to save a very simple image in .png for use on the net.

    .psd file is photoshop's version of .xcf except it is a more professional format and will save layers when using ps. it can also use cmyk color for printing when using ps.

    i can't remember if gimp can open the layers of a .psd file but inkscape can. so if you want to take apart a .psd file you can open it in inkscape and "ungroup" the objects. then export each as .png files.

    Yeah Gimp opens PS files, the only thing is it doesn't support layer styles.

    i just noticed that the original poster hasn't said weather any of this helped. it's best when people post the results of getting advice. that way others can benefit as well.

    so eX.A.K.R. where are you? ???

    but...
    *.gif can handle layers as an animation, but can it handle layers as an image?
    like if you open in gimp, you can se the different layers...

    Hi! I'm not sure this is the correct area where I should post this question, but I'm trying to make rounded corners ONLY on either the left side of a rectangled image or the right side of the image (.jpg). I KNOW how to make ALL corners rounded, but how do I go about making only two (or even only one corner) corners rounded? I've looked and looked and cannot find this information... I only find the information for making a 'rounded' rectangle. Anyone's help will be greatly appreciated!

    Thanks.
