Mine's too big...

[hummingberd]

I knew this would get some peeks. So, my pictures are huge. I can't figure out how to make them smaller. Help please.

Use photo editing software to resize the pictures.

if you don't have software to do it the gimp is a nice free tool

I'll second the Gimp comment. I use it to crop and resize my pictures, and it will do a lot more. I usually choose it over Photoshop which I also have access too.

If you simply want to resize pictures for the web and have a fast internet connection, many photo hosting services will resize them for you. I use photobucket, and have it set so that it will resize anything I upload to 800x600. If you do it that way, you still have to upload the full size picture (could be a few megs vs a few 100k for a 800x600). For uploading a bunch of photos, that can mean a large difference. I need write a script to batch resize pictures before uploading, that would save some time.

I get the impression you're using linux
check out mogrify
great for batch processing pics

I use both Linux and Windows (my wife is used to Win, and I still play games there too sometimes).

mogrify is part of ImageMagick and once you reminded me of it I realized I have already written a script that does it. ImageMagick interfaces well with lots of languages. I had used it in a perl script I wrote a long time ago to take a directory of photos, make thumbnails, and write a HTML page displaying them (an automated website update type thing). Now I just have to find it.

ImageMagick is also available on Windows and so is perl (ActivePerl). If I can find the script, maybe I put it up somewhere so if anyone wants they can use it (just don't laugh at my ugly perl - I'm self taught )

I wasn't aware there was any other kind of perl

Ok, if anyone is interested, I found my old script and edited it so that it just makes a 160x120 thumbnail and 800x600 resized image. It will do this for any jpg in the directory it is run in. If you need to resize a lot of pictures, it will make the job much easier.

This will run on windows as long as you have two things installed. You need Imagmagick and ActivePerl. I think it should also run an any other platform that has both perl and Imagemagick installed.

Here is the text of the script. You can just copy this text into a normal text file and name it resize.pl (or whatever you want ending with .pl)

#
use Image::Magick ;
@jpgs = <*.JPG> ;
mkdir "thumbs" ;
mkdir "800x600" ;
$pic_num = $#jpgs ;
$pic_count = $pic_num +1 ;
for ($a = 0 ; $a <= $pic_num ; $a++){
    $count = $a +1 ;
    $thumbname = "thumbs/$jpgs[$a]" ;
    $resize = "800x600/$jpgs[$a]" ;
    print "Working on $thumbname ($count of $pic_count)\n" ;
    $x = $thumb = Image::Magick->new ;
    $x = $thumb->Read($jpgs[$a]) ;
    $x = $thumb->Thumbnail('160x160') ;
    $x = $thumb->Write($thumbname) ;
    $y = $image = Image::Magick->new ;
    $y = $image->Read($jpgs[$a]) ;
    $y = $image->Resize('800x800') ;
    $y = $image->Write($resize) ;
}

It assumes that your jpeg images are named "xxxxx.JPG". If your images use lowercase file extensions (xxxx.jpg), you will need to change the line "@jpgs = <*.JPG> ;" to "@jpgs = <*.jpg> ;" Imagemagick is also smart enough to handle images that are rotated (meaning 800x600 vs 600x800). What it will actually do is make a thumbnail that is 160 pixels on its longest side and a resized image that is 800 pixels on its longest side. The aspect ratio will be conserved. If you want the thumbnails or images to be a different size, just change the "Resize('800x800')" or "Thumbnail('160x160')" to what you want.
