Try using the "Image IO" library from the standard JDK. I suggest 
installing "JAI Imaging IO Tools" so you will get some readers capable 
of reading embedded thumbnails in JPEG images.

If there is no embedded thumbnail in your image files, then just load 
the image with SWT:

Image img = new Image(display,filename);

and then resize it, with something like:

Image thumb = new Image(display,x,y);
GC gc = thumb.getGC();
gc.drawImage(img,0,0,sizex,sizey,0,0,x,y);

(this pseudo-code is surely not 100% correct, consider it just a hint).
