you might try using PaintShop Pro, I think it has a 'sharpen' function for sharpening images.
PSP is a shareware, available at:

or:

(many download sites for you to choose from)

if this helps, tell me and I'll re-post this comment as an answer.

If the image is a bitmapped image (.BMP) you'll be out of luck with getting good results. If it's a vector based image (.JPG, .TIF, .GIF), you should be able to do it with programs like arnond mentioned.

Hi momony,
If you want to enlarge the image, then you can usually get good results using Adobe Photoshop's (http://www.download.com/PC/Result/TitleDetail/0,4,0-57355,1000.html?st.dl.results.list.tdtl)or PSP's resample feature.  If you simply resize the image then the quality will be horrible.  As long as you aren't increasing the image's size too much, resample will work perfect.  You will probably want to increase the color depth as well if say the image was 16 bit, when resampling it up, you will want to increase it's color depth to the maximum, so that it has more color's to choose from.

I would always suggest resampling an image over resizing, when you are interested in quality.

I hope this helps you out!

Sincerely,
Jason

If it isn't a vector image your image quality will be poor when you are done.  You don't have enough colour information to start with to warrant crisp enlarging!

Since when are jpg and gif files vector based? The individual elements within the graphic cannot be selected and edited (such as is possible with most draw programs), there are no x,y coordinates designating the positioning of elements within the image.

Have I been misunderstanding the difference between raster and vector images all these years?

Use photoshop 5, but if you put trash in you`ll get trash out.

Oh and you are correct about Vector and Raster images Colleen. Bmp, Tiff, Jpeg & Gif are all bitmap images.  You`ll need Adobe Illustrator or Corel (spit!) for vector based images, that can be re-sized to your hearts content without quality loss.

One note, Stratford. You can resize vector images and maintain the quality only so long as they are vector images. To publish to the 'net, they will have to be converted to bitmapped images (jpg, gif, or png).

I woyld suggest looking at:
http://www.adobe.com/studio/tipstechniques/photorepair/main.html

Although this article focuses on digital photography, I have found the techniques useful for salvaging gifs and jpegs. Again you will need photoshop. Be sure to experiment with the layering options, as well as focus and contrast/brightness to acheive the best results. You will never have a perfect enlargement, but your results may be usable.
