Can I make a scatterplot with custom marker symbols?

MATLAB has a range of default symbols to use as point markers on a scatterplot (circle, asterisk, point, etc.). But is there any way of replacing these with a custom symbol? Specifically, I would like to give each point a thumbnail image representing the identity of that point. Is that possible?

Short answer: NO. User defined markers cannot be used in MATLAB.. Though you could draw (image) them in each location..
The markers in MATLAB are..
'+' Plus sign
'o' Circle
'*' Asterisk
'.' Point
'x' Cross
'square' or 's' Square
'diamond' or 'd' Diamond
'^' Upward-pointing triangle
'v' Downward-pointing triangle
'>' Right-pointing triangle
'<' Left-pointing triangle
'pentagram' or 'p' Five-pointed star (pentagram)
'hexagram' or 'h''' Six-pointed star (hexagram)
'none' No marker (default)

You can ry this example:
load discrim
h = gscatter(ratings(:,1),ratings(:,2),group,'br','xo');
hold on
troll = imread('http://ragecollection.com/img/ragefaces/trollface.png');
imagesc([680 710],[8800 8100],troll)

To show a practical example using Thomas' link in the comments:
% Sample scattergroup
load discrim
h = gscatter(ratings(:,1),ratings(:,2),group,'br','xo');
hold on
% Define the font and desired character (smiley)
font = 'Wingdings';
m = 'J';
% Use text to plot the character
x = get(h(2),'Xdata');
y = get(h(2),'Ydata');
text(x,y,m,'fontname',font,'HorizontalAl','center','color','r')
% Delete old markers
delete(h(2))
