25KB should be more than enough for a JPG file, even if only compressed slightly. Heck even using a lossLESS algorithm like LZH (as used in many .gifs) would still easily get a 100x100 JPG file under 25 KB.

Problem is that Photoshop by default includes a lot of extra stuff into saved files - for jpegs: be sure that image preview (a smaller version of the jpeg) isn't being saved in the file, and also be sure embedded information such as profiles are turned off - they generally aren't needed for images intended for the web.

Many consumer, and even free open-source, programs optimize better than Photoshop does ... give Paint Shop Pro or similar a try.

More smilies are coming - it's on my list of things to do.
